Why sells a broken plugin?
2 years ago I bought a shortcode, but the button didn't seem. Then I got a newer version, after you update Joomla button disappeared. I remained in the plugin.

Today I bought this plugin again, I thought the new plugin would work, but the button again doesn't appear. None of the versions does not work, neither older nor later. The button in the editor is not !!!!

Dear reznickovan,

Are you using Joomla 3.10? Please submit a ticket and send your ftp account, I will fix this issue for you.

Thanks
