Drupal 7 The website encountered an unexpected error. Please try again later -

I'm all,

I'm new to Drupal.

One of my DB exports / imports, I can not access my Dopplate administrator. I get this message: The website got an unexpected error. Try again later. I've read a lot on the forums and the Doppel site but nothing helps me.

In the stack I found something to print some more errors (below).

  1 array ('% Type' = & gt; 'PDOEception', '! Message' = & gt; 'SQLSTATE [HY000]: General error: 1364 field' wid 'default value INSERT {watchdog} (type UID, message, variable, severity, link, location, referenced, hostname, timestamp) values ​​(db_insert_placeholder_0 ,: db_insert_placeholder_1 ,: db_insert_placeholder_2 ,: db_insert_placeholder_3 ,: db_insert_placeholder_4 ,: db_insert_placeholder_5 ,: db_insert_placeholder_6 : [Db_insert_placeholder_7, db_insert_placeholder_8, db_insert_placeholder_9]; Array ([: db_insert_placeholder_0] = & gt; 1 [: db_insert_placeholder_1] => User [: db_insert_placeholder_2] => is closed for session% name. [: Db_insert_placeholder_3 ] = & Gt; a: 1 : {S: 5: "% name"; S: 5: "Admin";} [: db_insert_placeholder_4] => 5 [: db_insert_placeholder_5] => [: Db_insert_placeholder_6] => Http: // dev .herbosch-kiere.be / en / user / logout [: db_insert_placeholder_7] = & gt; http://dev.herbosch-kiere.be/en [: db_insert_placeholder_8] = & gt; 91.177.201.173 [: db_insert_placeholder_9] = & gt; 1414422871) ','% function '= & gt; 'Dblog_watchdog ()', '% file' = & gt; '/data/sites/web/eiffagebeneluxbe/Filiales/HK/modules/dblog/dblog.module', '% line' = & gt; 160, 'severity_level' = & gt; 3,)  

I tried a lot:
- Watchdog is empty in DB.
- Install new drops - - ...

Any ideas?
