I noticed today at the very bottom of the page it says

Notice [PHP]: Only variable references should be returned by reference in file language/english/local.php line 43
Notice [PHP]: Only variable references should be returned by reference in file kernel/module.php line 1349


I haven't edited the site in a while so Im not sure how long its been there, but I can't figure out how to fix it. Im using version 2.2.3a

Any help would be appreciated

Have you tried turning Debug Mode off in
Preferences > General Settings

That's right, just turn debug off. It's only a php notice, it means something to programmers but it's not a problem.
