Hi,
Thanks for letting me know. This was a new bug, a typo in the sql statement for MySql. I've corrected it and uploaded a new mojoportal-2-2-7-7-mysqldatalayer-GPL.zip file with the fix. The only file you need to replace is mojoPortal.Data.dll, get it from the new zip and put it in the Web/bin folder overwriting the existing one. It should fix the problem.
Best,
Joe
