Hello, I need help with this fatal error: (paths deleted for easy reading)
```
Fatal error: Uncaught Exception: Unable to open file /extensions/CookieWarning/extension.json: filemtime(): stat failed for
/extensions/CookieWarning/extension.json in /includes/registration/ExtensionRegistry.php:136 Stack trace: #0
/includes/GlobalFunctions.php(52): ExtensionRegistry->queue('/kunden/vexilli...') #1 /LocalSettings.php(322): wfLoadExtension('CookieWarning') #2 /includes/Setup.php(124): require_once('/kunden/vexilli...') #3
/includes/WebStart.php(81): require_once('/kunden/vexilli...') #4 /index.php(41): require('/kunden/vexilli...') #5 {main} thrown in
/includes/registration/ExtensionRegistry.php on line 136
```
The error occurred after installing this extension with these local settings:
```
wfLoadExtension( 'CookieWarning' );
$wgCookieWarningEnabled = true;
$wgCookieWarningGeoIPLookup = 'none';
```
These lines are now commented away (auskommentiert) to let the wiki run.
I would rather not make the error visible again because then the wiki would be blocked until the technicians have visited it. I can only do this for some minutes if really needed.
I am running Mediawiki 1.34.1 in Google Chrome browser Version 86.0.4240.183 (Offizieller Build) (64-Bit).
