I just installed this plugin on a new WP install. First thing I noticed: when you click ‘view details’ on a plugin (installed or in resp.), no more pop-up but a new page. My WP menu bar, which was collapsed, stayed that way cos PepiPost broke the working of that button too.
There were many more issues, but I think a WP plugin that doesn’t play nice with WP is just … well, it shouldn’t even be listed in the repository, I think.
