Our company has offered both TinyMCE and ATTO text editor plugins for a while now. However, we've found that sometimes our plugin buttons do not show up in the text editors. They are correctly installed and configured (under the respective toolbar config), and both dependency plugins are also installed correctly.
At first this issue arose with Moodle version 3.0.5 and above, with both the newer and older versions of both plugins, however I'm now seeing the issue in a Moodle 2.8 installation that I am using to run tests. The plugins have worked fine before on several Moodle versions, and I'm seeing no errors reported either through developer debugging or in the database logs table.
Is anyone aware of, or has anyone else experience a problem with their text editor plugins not showing up in the toolbars?
Any responses would be greatly appreciated.
