Summary
When I use the installer to update Tinymcerte to version 3.0.1, the editor does not load. Yes I cleared the cache for MODX and the browser, tried different browsers, and reinstalled.
It appears the manager is still trying to load the 2.1.1 (TinyMCE) javascript but gets 404s.
I was able to make it work by completely removing the extra and then starting by downloading the 3.0.1 package.
Environment
All the latest versions (MODX, php8.3) on MODXCloud.
