Some special characters will cause it also. The software developer is working on fixing this. Weird things like exclamation points and the like can cause it to not appear. We hope to have a fix from them soon, they have been promising it for two months since this started after an upgrade. So try not putting gang extraneous punctuation marks in your posts.

Please read the thread started about two months go on missing posts. That pretty much speaks to all the work arounds we have found while waiting for the fix.
