I have the Dev version of of CJT and I am installing it on a new installation of WP. The installation is vanilla 3.8.2 and following the instructions to activate the license. I check the license key and the plugin installed verifies that it is valid, but it won’t let me activate it from within the plugin. The plugin says that it must be activated from your site.
So I logged in and tried to add the domain through the manage sites area for view license. I put in the domain that the has the plugin installed and click add site. The browser bar turns showing a submission but your site refreshes the page and no entry was added.
