LuaXML error: "undefined symbol: luaL_prepbuffer" - module

I'm using the lua interpreter and I'm trying to load LuaXML but when I require('LuaXML'), I get this error.
lua: error loading module 'LuaXML' from file './LuaXML_lib.so':
./LuaXML_lib.so: undefined symbol: luaL_prepbuffer
I have no clue how to fix this. I tried compiling the module myself but it still throws the error.

This is because you are trying to use LuaXML under Lua 5.2.
LuaXML was designed for Lua 5.1.
The problem can be solved by installing Lua 5.1.x or LuaJIT.

Problems with php-gd in php8.1

I have php8.1 running on FreeBSD 12.
Install php81-gd and having a trouble to start php due to the following error:
Any guess how to fix it, please?
PHP Warning: PHP Startup: Unable to load dynamic library 'gd.so' (tried: /usr/local/lib/php/20210902/gd.so (/usr/local/lib/php/20210902/gd.so: Undefined symbol "gdImageCreateFromAvif"), /usr/local/lib/php/20210902/gd.so.so (Cannot open "/usr/local/lib/php/20210902/gd.so.so")) in Unknown on line 0```
You probably need to upgrade the libgd package as well with pkg upgrade libgd; for whatever reason the package manager doesn’t seem to do it automatically when you install the php81-gd package.

PHP Fatal error: Uncaught Error: Class 'Phalcon\\Db' not found. for Phalcon 4

I am currently upgrading version PHP 5 to PHP 7. And Phalcon 1 to Phalcon 4.
my all existing API gives error.
Fatal error: Uncaught Error: Class 'Phalcon\Db' not found.
I have found that use Phalcon\Db\Enum instead of Phalcon\Db.
but I want to use Phalcon\Db. Is there any way to use?
Please help me as because of this I have made many changes in my project.
As per phalcon's docs for phalcon4.0 you will have to use ENUM
https://docs.phalcon.io/4.0/en/api/phalcon_db
You can use phalcon3.4 in case if you want to use Phalcon/Db

How Can I Clear A Kotlin Error in JavaFX?

I was trying to fix an error in a JavaFX program from an on-line course. In researching someone said moving a file cleared the error.
When I moved my todoItemDialog.fxml file it gave me this error even though Kotlin is not involved:
Error: Kotlin: The Kotlin standard library is not found in the module graph. Please ensure you have the 'requires kotlin.stdlib' clause in your module definition.
When I add the statement to my module-info.java tab in IntelliJ Idea is gives this error:
Module not found: kotlin.stdlib
I removed the requires statement and moved the todoItemDialog.fxml file back to it's original location but I still get the Kotlin error.
How can I clear the Kotlin error without starting over from the first line of code for this project?
I encountered this same error while running JavaFX code. Simply rebuilding the project will solve the error.
Build -> Rebuild Project

Prestashop 1.6.1.4 - Undefined constant for custom module

We have upgraded from Prestashop 1.6.0.9 to 1.6.1.4. After updating to new version one of our custom module started throwing Fatal Error like :
PHP ERROR
We have defined this constant in the classes/pdf/PDF.php file.
I am not able to trace the error as it was working previously. Any help or reference will be appreciated.
Try to define this constant in your custom module like that:
if (!defined('TEMPLATE_PRODUCT_RETURN'))
{
define('TEMPLATE_PRODUCT_RETURN', '...');
}
