PHP Warning: Module already loaded in Unknown on line 0

This error message usually indicates that a PHP extension is being loaded more than once in your php.ini configuration file. This can happen if the same extension= or zend_extension= directive is declared multiple times, or if multiple configuration files are loaded that both include the same extension. To fix this error, you should ensure that each extension is only declared once.

There are a few different ways you can do this:

1. Locate the php.ini file used by your PHP environment.
2. Search for duplicate extension= or zend_extension= directives and remove or comment out the extra lines.
3. Restart your web server or PHP-FPM process to apply the changes.
