Error “Undefined array key” (FIXED)
-
Sorry I was unable to reply to the thread with the original poster’s error message. Here is the fix…
I patched the plugin, so it now checks whether those URL parameters exist before using them. I also corrected $current_user->id to $current_user->ID, added nonce protection handling, and added exit; after the redirect.
Save the following code as user-avatar.php
Please make a backup copy of the file first!!!
