My site got Error Database query error

Did you not get an email report when it happened? If you have a backup try to restore and try again.

yeah, Now i fix it thanks you

Can you please inform us how you fixed it? Thank you.

Oh, After I update the 12 version, then I update the mods too. Before I didn't update the mods.  One of the mods was give the error. Also, clear the cache too.

you are doing better than I. About 8 days ago I purchase the Professional Plan and started to update my v 14.04 site and add mods. Shortly after trying to add some mods i started to get errors which looks like version incompatibilities since the had 12.0. Now my sys_accounts table is missing all but the two original dolphin pro trial accounts which i can not log in to. At this point my site is showing public content with out the ability to log in or signup. I am not sure if it was hacked, file corruption, or update problem.

Most apps are not ready 12 version, so you have to wait to full version or you can ask app Creater to fix for temporary so you can run your site until you get 12 full version
