I too have been getting this message with my users’s blogs, despite having activated the plugin on their sites for them:
“Sorry, but you do not have the correct permissions to install the Option Tree plugin.”
I am sure it has to do with file/folder ownership/permissions, but can’t seem to get it right. The theme I am using is Widescreen, but have seen it on other GPP themes, as well.
Anybody have any suggestions?
