500 Internal Server Error

[Osama89]

Hello, 
I am having this message "500 Internal Server Error" when I am trying to open my website, back-office and the main site.

This happened when I did a restore to my website after updating it to the last version with the module 1 click update.

Any ideas on how I can fix the problem, and try to connect to my website ?

Thanks.

Enable debug mode / depend on version clear cache in VAR folder.

I don't know how to do that, I can't access to my back-office at all, is this screen shot help?

This is one of the core tables that is missing, check you database!

Can I do a rollback, for the database before the update? Will it solve the problem?

[JBW]

Yes you can manually restore the database

Thanks a lot, I contacted the Support Technique of o2switch, and they restored my database, it's worked now.
