As I stated there is most likely something wonky with faq.php that prevents the global query from running.
I have an idea but the easiest thing is just because the issue is located just on that script turn off the queries like so. Like the query portion of the global variables plugin would look like this now if your using mysqli.

You can send us an admin login through the contact us link if you want but if you basically if you look in bold above at top of the query section I added an if clause to not run queries of on faq.php and at bottom of the plugin I add the closing bracket for the if clause. That solves the issue.
