Where do I report a problem of posts flashing on screen and then disappearing.

Hello Everyone

I have created a thread for Balgavies Loch Ospreys.    

The posts flash on the screen then disappear.  

I have managed to get some to stay on the screen, but when I add photos which are only 51.9 kb this problem happens.   When you edit the post the information is still there but it will not stay on the screen when posted.  

Has anyone else encountered this problem, also the last post I made was only text and it also disappeared from the screen.  

Very frustrating and puzzling.  

Any help would be appreciated.
