Hi

I have copied a mediawiki 1.33.1 from a server to another.

The original is working fine here : https://gestinux.net

I know that I must upgrade, but first I have to move it without changes to another server able to run a supported php version.

I have made myself a small extension using an hook.

On the new site https://test.gestinux.net I get this error, with the same code in the extension :

[X-767HO9Cu8SMC0GF1o@bgAAACM] /mediawiki/index.php?title=Main_Page MWException from line 164 of [path]/mediawiki/includes/Hooks.php: Invalid callback LanguageLinksHook::onOutputPageBeforeHTML in hooks for OutputPageBeforeHTML

With stack ending with :

#0 [path]/mediawiki/includes/Hooks.php(234): Hooks::callHook(string, array, array, NULL, string)

Even if the hook does nothing, I have the same error :

   public static function onOutputPageBeforeHTML( OutputPage  &$out, &$text )

       {

       return true;

       }

Where can be the problem ? I'm stuck !

I'm running php 7.2 and warnings are enabled on the test site.

The "PHP class autoloader" is probably not set up correctly. It looks like The class `LanguageLinksHook` can not be found. Check if you have set up the autoloader in your `extension.json` file

• Manual:Extension.json/Schema#AutoloadClasses
• Manual:Extension.json/Schema#AutoloadNamespaces

Thanks !
