Fatal error on extention

Hi guys,

I am a bit lost what is going on here. I would like to know and learn :-)

I installed the module artists_catalog. It worked fine, until I tried to ad another module from it. So I decided to remove it completely by uninstalling.
Database tables where gone, cache cleared.

Did a new install.
But I cannot get it to run again.
I get a fatal error when trying to create a new portfolio entry. I can see my created data in the table of the database, but apparently something is missing/going wrong.

Maybe somebody can push me in the right direction:


Fatal error: Uncaught exception Exception with message Query error: Unknown column 'page' in 'where clause' (SELECT * FROM tl_ac_project WHERE page=NULL) thrown in system/modules/core/library/Contao/Database/Statement.php on line 283

Maybe better to create a ticket here https://github.com/codefog/contao-artists_catalog
