So I was in my FTP and saw my error log sitting in there and transferred it over. It looks like this is the problem:

[26-Jun-2015 10:44:02 US/Pacific] PHP Fatal error:  Class 'BASE_MCLASS_EventHandler' not found in /home/bgcco/public_html/ow_system_plugins/base/mobile/init.php on line 83

This is the code from line 70 down in that file:

=================================================

this is way out of my area. anyone know what we're looking at here? :D

I would strongly suggest disabling the mobile version all together. It's rubbish.

I prefer to get it fixed. Sorry, I put the wrong init.php code in. That was for the desktop. This is for mobile and line 83 is 3rd from last (86 lines total):

What's really bizarre is between June 19th and today, I've had 10,000 of these fatal errors in my error log, so something weird is going on. I have 10,800 lines of fatal errors and starting from 455, every one is the problem with the init.php file for mobile. They started 7 pm Pacific time and I was in Rhodes, Greece that morning (would be the 20th) so I wasn't making changes to the site while I was away.

Anyone understand the code enough to even understand the problem?

Wow. So I solved it! Really crazy and I don't think anyone could have figured this out for me given where the problem was. But thank you, Bobbi, for getting me to the error log to find the problem. Now I know where to go next time.

So...I ended up looking through each file to match it up with the original script. Amazingly, for whatever reason, the base/mobile/classes/eventhandler.php file was there but read 0 bytes. The original read 26kb. No idea how this happened but once I replaced the file, the mobile side started working.

So thank you for those who tried to help and did help. That was kind of a needle in a haystack but Bobbi pointed me to which haystack to look in. ;)

Thanks for letting us know the reason and solution of the issue. I'm going to mark this thread as Solved then.
