This is a different thread than the “Edit button doesn’t work”, and a different site. That’s over here: https://simple-press.com/support-forum/sp5-general-topics/edit-button-does-not-work/
I have Simple Press 5.1.1, latest plugins. I have the TinyMCE editor set.
I’m running on WPEngine which has its own caching (they don’t allow caching plugins, they handle it on their own). http://wpengine.com.
Clicking on the broken buttons does nothing. The URL shows “javascript:void(null)” when it’s a broken button.
The Add Topic button (from the main forum list) does nothing as well. Add Topic (from within a single topic) takes me to the main forum list.
