OMG I figured it out!!! Thanks to your pushing in the right direction I discovered something...

When you said to check the functions.php file I looked thru it at the part you specified and didn't really see anything that I could change. HOWEVER, below that section I noticed


Which made a light bulb light up in my head! It made me think about the datastore file that is referenced in the config.php Remember how I was saying earlier that I had been moving the ENTIRE SITE including database AND filesystem and that the ONLY FILE that was different was the config.php. Well so I commented out the
//$config['Datastore']['class'] = 'vB_Datastore_Filecache';
in the config.php file and VOILA!! Style chooser is now working again!!!

BUT unfortunately the fun doesn't stop there.

- I go back into the config.php and uncomment $config['Datastore']['class'] = 'vB_Datastore_Filecache';
- Delete the datastore_cache.php file and replace it with a stock vB datastore_cache.php
- Then I go into the AdminCP -> Maintenance -> Update Counters -> Rebuild Styles

But then the problem is now back again, missing style chooser. So apparently clearing out the datastore_cache.php file is still causing it to rebuild the style cache with whatever issue is in there. I was thinking ok maybe there is something wrong with one of the styles but as I stated before it does this to the Default style as well. Also as I mentioned when I comment out the datastore line in the config.php file to disabled datastore caching the style chooser starts working fine again.

I even tried going into the config.php and disabling all my plugins, and then retrying the procedure I listed above. Still did the same thing. So I don't think it's a plugin issue.

Any ideas?

Thanks again for your help though, if you hadn't shoved me into the right direction I wouldn't have seen that line in the functions.php file referencing datastore cache and that damn light bulb would have never gone off in my head lol :D

Ok after some more research now that I had some more ammo to search with via Google I have found that this is apparently a bug in PHP v5.2 which is what my HOST uses on their servers. The reason that this wasn't happening when I was putting the forum on my local server is because I am running PHP v5.3

The solution that worked for me to fix the issue is referenced in the last post on this page...
