Hello, just discovered a big problem after accidentally upgrading to WordPress 6.5 and after debugging I found that the combination to generate it.

It can be easily reproduce by install a fresh version of

• WordPress 6.5
• Latest version of Divi
• Latest version of Modula

No other plugins installed.

The error is the following:

Fatal error: Uncaught TypeError: Argument 2 passed to WP_Translation_Controller::load_file() must be of the type string, null given, called in C:\laragon\www\wordpress\wp-includes\l10n.php on line 838 and defined in C:\laragon\www\wordpress\wp-includes\l10n\class-wp-translation-controller.php:101 Stack trace: #0 C:\laragon\www\wordpress\wp-includes\l10n.php(838): WP_Translation_Controller->load_file(‘C:\laragon\www\…’, NULL, ‘en_US’) #1 C:\laragon\www\wordpress\wp-includes\l10n.php(1005): load_textdomain(NULL, ‘C:\laragon\www\…’, ‘en_US’) #2 C:\laragon\www\wordpress\wp-content\themes\Divi\includes\builder\api\DiviExtension.php(266): load_plugin_textdomain(NULL, false, ‘includes/langua…’) #3 C:\laragon\www\wordpress\wp-content\themes\Divi\includes\builder\api\DiviExtension.php(126): DiviExtension->_initialize() #4 C:\laragon\www\wordpress\wp-content\plugins\modula-best-grid-gallery\includes\divi-extension\includes\DiviExtension.php(16): DiviExtension->__construct(‘modula-divi’, Array) #5 C:\laragon\www\wordpres in C:\laragon\www\wordpress\wp-includes\l10n\class-wp-translation-controller.php on line 101
