After last update 5.0.6 there is unable to save created new or existing survey due to error:
Save failed with the following error: Unknown column 'typeAlias' in 'field list'"
This is urgent thing, we cannot use surveys on production site.
Edit: Problem exist with version 5.0.7 that can be obtained only by update system.
Reversion to 5.0.6 version from download area solve the problem. But version 5.0.7 is not covered in changelog, so I dont know what this downgrade can make a mess.
