Thread:Extension talk:MobileFrontend/ResourceLoaderModule.php on line 469 Warning: file exists(): open basedir restriction in effect./reply

It appears you're trying to access files from another user account on your server. Notice how the user home directories don't match in your errors:

File(/home/a9894545/public_html/wiki/../png) is not within the allowed path(s): (/home/u669937943:/usr/lib/php:/tmp) in /home/u669937943/public_html/wiki/../ResourceLoaderModule.php on line 469

This is an error raised by your server environment, not MobileFrontend. Presumably you moved your wiki around on the server, and the new location is still trying to access the old location, except that the old location is owned by a different user account which the new MediaWiki is not allowed to access.

See also Manual:Moving a wiki. You might have to run update.php to clear additional caches that might refer to the old directory still.
