For some reason, recently, several users are unable to post on certain threads/posts. They do have the permission - I have recently come across the issue myself. We are on 1.2.1 and are planning to update. This is happening on DEFAULt/vanilla theme as well as our purchased PixelEdit theme. Below is a screenshot It highlights like it is going to post but doesnt do anything and then eventually goes back. I have tried Firefox/Chrome and both do not work. I'm thinking something got corrupted and not sure an update to 1.2.2 will fix the issue. Any idea?
