How to fix this problem

Hi I just upgrade to 7.7 and when i login shows a lot of strange stuffs take a look to the attached pic .

Hope someone help to resolve this problem

Thanks. 

Clear your cache.

This is a CSS issue. Your running a custom template by the looks of it, so switch to the default UNI template and see if it happens there as well.

I did replace template to UNI and still same thing after I clean cache and cookies any pther idea?

Have you tried joining as another test account?  Can you provide a test login/account.  Looks like theres a database query error.

well  I just received to emails about data base error see attachment

Looks like your missing the "Nickname" field for the join form.  Showing duplicate nickname as error. As for the issue with showing "strange stuff",  if you already did what Deano suggested, it would help for you to provide login for test.

Thanks

And you have cleaned Cache and Cache_Public  via  FTP manually, correct?

yes

Not sure but it seems like you have a css issue mixed with another template.  It's calling for background image and theres several templates I see.

You can disable cache for css files in admin-->settings-->advanced-->template  to  check further, but I would take care of database errors first..
