MyBB Community Forums

In my 1.4 test forum I could upload a theme but now I wanne do it in my upgraded forum and I get this message.

MyBB could not find the theme with the file you uploaded. Please check the file is the correct and is not corrupt.

This theme is 100% sure for 1.4 and later

When you rename the theme i've got that problem also.

what version of mybb are you using?

1.4
1.4.1
1.4.2

I think the problem was that I change the configuration of the theme in my testforum that way that it becomes bad what means I cannot imort it as file.
I add the whole code by copy and past and then it works correct.

It's a problem with the XML. For some reason MyBB sometimes exports incorrectly and some tags are missing in the XML file.
