Just like Eric I’m getting this error. And installing a new copy didn’t fix it for me.
I have it installed on my local XAMPP server and accessing it through http://localhost/mmcms/index.php. I left all the settings at it’s default value and installed the default site.
In Chrome 5.0.375.125 and Safari 5.0 (6533.16) the editable region just deactivates (yellow background disappears), but in Firefox (3.6.8) the editable region gets hidden.
Any ideas?
Greetz,
