I am adding a new SSL specific error code inside SSLerrs.h in Mozilla NSS.
My question is, which file that contains the html page for that error? Because I need to modify the page too - to add my own messages.
Thanks.
/docshell/resources/content/netError.xhtml is the generic UI for network errors, including SSL errors.
/security/manager/locales/en-US/chrome/pipnss/nsserrors.properties contains translations of SSL_ERROR_* to user-visible strings; see also other locales.

I'm getting an issue in Lucee when my file size is greater than 64KB, it shows an error "Method code too large!".
I also attached a screenshot below, please check and help me to resolve this issue.
Lucee obviously has a limit regarding the size of methods. The error message already provides all the information you need.
You should split up your code into several files. This can be done by moving out parts into different templates, i.e. CFM files, and then include them in your main CFM via <cfinclude>. Or alternatively, you can move the code into components, i.e. CFC files and instanciate them via createObject() in your main CFM.
When Yii2 is used in debug mode and an error occurs, it shows a error message along with call trace, session, cookie and server info.
Sample image shown below.
In production ready systems, this will not be shown. However, Is there a way to pull this formatted html into a variable in production systems, so that it can be emailed to the developer to ease in debugging errors. If any one has any idea, please let me know.
I tried using \Yii::$app->mailer->render() passing #vendor/yiisoft/yii2/views/errorHandler/exception.php as view, ['exception => $ex] as data, layout file as parameters. I'm getting undefined variable handler error.

We had a problem with some of our IE clients failing to download a PDF, even after clicking on the link. We found the answer here resolved our problems: set forcedownload=true for PDF mime types in web.config.
However, that created another problem: we are now unable to render a PDF in a browser when we want to. We used to do this with an iframe. However, as you can see, the PDF just downloads, and does not render in the browser.
I learned that the forcedownload=true setting is actually a default in a subsequent version of Sitecore (v7.2). So, I'm hesitant to revert that.
So, how do I render a PDF in a browser in this situation?
You can leave forceDownload=false on the PDF mime type and instead set the following setting to false:
<setting name="Media.EnableRangeRetrievalRequest" value="false"/>
I faced the same dilema a few months back with the same initial fix. Found out the actual issue last week, I wrote a blog post about it. (In fact, I wrote the answer you linked to, I've updated it with the same information now for future visitors)
The issue is basically a combination of Adobe Reader plugin for IE9, chunked transfer encoding and streaming the file directly from the database. I found if you close your browser and try again, or force refresh with Ctrl+F5 it worked fine. Once Sitecore had cached the file to disk it would continue to work for everyone.
The above setting disables chunked transfer encoding, instead sending the file down to the browser as a single piece. This setting was introduced in Sitecore 6.5+
This is one of the flaws in the MediaRequestHandler and in my opinion; the forceDownload option is pretty useless the way it is designed by default. (Why would ever want to configure this option on media extension only?)
You’ll have to basically turn off the forcedownload option again and replace the MediaRequestHandler with your own one. I usually end up with writing my own anyway because if other issues with the default handler, such as dealing properly with CDN’s etc.
In the ProcessRequest pipeline, you can determine if the item should be “downloaded” or not by setting the Content-Disposition header. You basically need to get rid of the default handling of forceDownload and set your headers based on your own logic.
Personally I prefer to set a query string parameter, such as ?dl=1, and base the Content-Disposition header on this. You could also extend the MediaItem template to contain a default behavior on each item or sub tree (leverage from Sitecore inheritance and standard values), and potentially you could thereby also define (override) a specific filename on each item for the attachment part in the Content-Disposition header.
When rendering the link, you can leverage from the properties collection (write a suitable extension method or similar), so that you can clearly mark your code that the link is meant for download, but still leverage from the built in field render methods. Thereby you eliminate the risk of messing up the page editor etc.

You have to disable range retrieval request in web.config by setting its value to false.
<setting name="Media.EnableRangeRetrievalRequest" value="false" />
MediaRequestHandler enables Sitecore to download PDF content partially in range using HTTP 206 Status code. You can also overwrite MediaRequestHandler and write your own custom implementation to handle media request.
I am curious about the proper way to stop a user from activating my plugin if their system does not meet certain requirements. Doing the checks is easy and I don't need any help with that, I am more curious how to tell WordPress to exit and display an error message.
Currently I have tried both exit($error_message) and die($error_message) in the activation hook method. While my message is displayed and the plugin is not activated, a message saying Fatal Error is also displayed (see image below).
Does anyone know of a better way, that would display my message in a proper error box without displaying Fatal error, it just looks really bad for new users to see that.
Thanks for any help in advance.
This is a little undocumented, as you might have noticed. Instead of die(), do it like this:
$plugin = dirname(__FILE__) . '/functions.php';
deactivate_plugins($plugin);
wp_die('<p>The <strong>X</strong> plugin requires version WordPress 2.8 or greater.</p>','Plugin Activation Error',array('response'=>200,'back_link'=>TRUE));
The lines above wp_die() are to deactivate this plugin. Note that we use functions.php in this case because that's where I have my Plugin Name meta data comment declaration -- and if you use a different file, then change the code above. Note that the path is very specific for a match. So, if you want to see what your path would normally be, use print_r(get_option('active_plugins'));die(); to dump that out so that you know what path you need. Since I had a plugin_code.php where the rest of my plugin code was, and since it was in the same directory as functions.php, I merely had to do dirname(__FILE__) for the proper path.
Note that the end of the wp_die() statement is important because it provides a backlink and prevents an error 500 (which is the default Apache code for wp_die()).
It is only a idea though. Try checking the wordpress version and compare then use php to through custom exception/error. PHP 5.0 try catch can be a good way to do it. Here is some resources.

You can try the first link. It is pretty basic. Thanks! hope the information will be helpful.
When selenium tries to open popup window I'm getting JS error permission denied in file
file:///C:/DOCUME~1//LOCALS~1/Temp/customProfileDir8708f7f69e14482ba857f4b2e74775c1/core/RemoteRunner.hta
So this break script execution, could you assist? I saw a related topic at MSDN and openqa but didn't find resolution that could help me.
I've just encountered this error. In the end it was because I was running IE in 'Offline' mode. Open the File menu and make sure that "Work Offline" does not have a tick next to it.
I've just updated a section about that in the Selenium docs. The website build is not working right now, so if you go to the site you will find the old version.
I'll paste the raw text here, I think your case is the second: JS trying to access sections that are still not loaded, so your solution would be a waitForPopUp command:
Why am I getting a permission denied
error?
The most common reason for this error
is that your session is attempting to
violate the same-origin policy by
crossing domain boundaries (e.g.,
accesses a page from http://domain1
and then accesses a page from
http://domain2) or switching protocols
(moving from http://domainX to
https://domainX). For this to be
solved, try using the Heightened
Privileges Browsers if you're working
with the Proxy Injection browsers.
This is covered in some detail in the
tutorial. Make sure you read the
sections about The Same Origin Policy
and Proxy Injection carefully.
If the previous situation was not your
case, it can also occur when
JavaScript attempts to look at
objects which are not yet available
(before the page has completely
loaded), or tries to look at objects
which are no longer available (after
the page has started to be unloaded).
This is most typically encountered
with AJAX pages which are working with
sections of a page or subframes that
load and/or reload independently of
the larger page. For this type of
problem, it is common that the error
is intermittent. Often it is
impossible to reproduce the problem
with a debugger because the trouble
stems from race conditions which are
not reproducible when the debugger's
overhead is added to the system. Try
first adding a static pause to make
sure this is the situation and then
moving on to the waitFor kind of
commands.
