Help with arcade scores not saving

I did an upgrade of my vbulletin forum to 3.7.0, since then my arcade (v2.6.7+) is showing the following error:



can anyone explain why this is happening and what steps I can take to rectify it? It does it on nearly all the games, and they were working perfectly before.

Thank you!

There seems to be a lot of score submission errors at the moment. We need Mr Zeropage to look at a fix when he gets back.

seems you forgot to import and overwrite the XML-file for 2.6.7+

Check your AddOns, I guess ibProArcade is still 2.6.6+ there
