please help! admin crashed

[maxf5]

Hey,

i just added some fields to a template. After long loading time suddenly the backend changed from "Reno" to the default admin theme without a cause.
I went back to the tree view and suddenly all i can see is attached: 


I worked 2 weeks on the site. Everything was fine..

So it seems that no default language is set? 

I deleted my cookies to logout from the admin: now i have no permissions to view the backend..

I've never had this problem but I'd swap /wire/ with a new one and move templates to elsewhere. Then I'd add template files one by one to find where the problem is.

Hey @abdus,

my files (/wire and /templates) are fine. I duplicated the files on a local xampp with a database clone of the site 1 week ago.
Then it works fine. If I import the live-version database, i have the same problem.
So something crashed inside the db.. permissions/page-rights or languages.

I've looked at the lines given in the error report, they all point to $language ($user->language) but can't access it. If you can access your database (adminer, PHPStorm, phpMyAdmin etc) examine field_language table. Confirm that your current user (admin = id: 40) has a language associated with it. Also see if $pages->get(<languageid assc. with admin>) returns anything

try repairing the database, also this may be related (?)

thanks for everything @abdus !
I merged the database of the crashed one with the backup db. After some trys it worked again : )

I still don't know how did that happen, added three fields to a template in the backend -> Reno crashed -> Default Admin Theme worked for 5 seconds -> then these errors.
It was a PW 3.0.71 installation. Well, hope won't happen in future.
