I updated my wiki and then saw my wiki page. Everything was great until I went to login. Now it says:

"

The omegafleetonline.com page isn’t working

omegafleetonline.com is currently unable to handle this request.

HTTP ERROR 500"

there's nothing wrong with the server since it was just working.

Check the error log of your web server, or temporarily set $wgShowExceptionDetails in the settings. There are many ways to find what is causing an error.

This is what I now get:

"Fatal error: Call to undefined function wfMsg() in /home6/omegafle/public_html/wiki/extensions/MultiUpload/MultiUpload.php on line 47"

correction, this is what I now have:

Fatal error: Call to a member function getIP() on null in /home6/omegafle/public_html/wiki/includes/user/User.php on line 2096

It wasn't this hard to set it up 5 years ago. Is there someway I can just fix it so it works properly?

According to the Error Log:

"

HP Warning: preg_match(): Compilation failed: group name must start with a non-digit at offset 8 in /home6/omegafle/public_html/wiki/includes/MagicWord.php on line 860

[03-Sep-2016 01:27:53 America/Denver] PHP Warning:  preg_match_all(): Compilation failed: group name must start with a non-digit at offset 4 in /home6/omegafle/public_html/wiki/includes/MagicWord.php on line 834"

Are you sure you're following Manual:Upgrading? By the error messages it looks like you're not. One of the things the manual says is to get and upgrade extensions as well, and not unpack the new installation files over the old installation!!
