Yes, I already got this error when testing with the 3.3 release candidate. I reported it to Joomlart on april 29th with the remark that it would be very helpfull (and pro active) to test and correct it BEFORE they release the new may template. But Joomlart has not been testing on joomla 3.3 at all….so the thememagic problem also exists with the freshly released JA Sugite.
At this time Joomlart templates are compatible with Joomla 3.2.3…… they will work with 3.2.4 and 3.3.0, but on 3.3.0 thememagic is malfunctioning.
We just have to wait until joomlart releases a new version………..
