I have the paid version of the plugin as well as the free version on serveral other blogs. The editor is broken after the latest update and when I filed a support ticket, their admin has posted spam on my site using the admin account provided for troubleshooting and nothing has been done about the problem. I want a refund!
Update: Their support has resolved the issue I had raised the ticket for. They are insisting that my blog must be hacked and denying that they posted the spam blogs. I am investigating logs and such further. So far there is no other indication of anything being out of the ordinary. Regardless, the plugin is working as intended at the moment, there has not been any further spam. The issue is resolved. The plugin is useful and does what it says. I have been using it for several years on several blogs without any other major issues.
