I have the same problem on DETC.nl , however on my other site’s Carmanscan.nl and SmokeWizard.nl this problem does not seem to appear (update 2.15 problem is solved) I switched the DETC.nl site back to twenty-ten then removed MapPress and reinstalled. No succes (thought it might had to do with the Theme I am using)
In PhpMyAdmin I can see that the databases are present. Any solution?
