Error upgrading to 3.x when WYSIWYG patch was used

Please try it without the patch to see if that is the problem. If so, report the problem with the patch on that issue.

The patch does not work with version 3.x, so I could not install it with it, however my contents were saved with the patch activated on 2.x, I think that is where the problem comes from

It seems that this new patch is working for me :
