Everything went fine, but I noticed some of the plugins weren't working correctly. I decided to deactivate, and update them manually one by one just to make sure everything would run smooth and current.

The minute I did it too the mailbox, boom, 500 error. Can't access any portion of my website. I tried going through cpanel, re updating 1.5 there, the mailbox update there, everything I could think of....

I'm at a loss on how to fix this, and would appreciate any help.

Thank you
