Backup of mysql failed : mysql::execute_sql failed : SQL select distinct host from user where user = ? failed

[vander.host]

Still no luck.

But I can simulate the problem in another way.

I click “manage” on the database, and I get this:

Fatal Error!
SQL select table_schema,table_name from information_schema.views where table_schema = ? failed : You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''' at line 1

Help!
