In the past two or three days the pages my messageboard has been running very slowly. Members from several different countries are complaining. I assumed it was something to do with the server at our web host. But I asked them and they said that nothing has changed there, and that no-one else using that server has commented. I don't have anything else besides the board on this particular server, so I haven't been able compare speeds of anything else.
Any ideas of why the board is suddenly running so slowly, or what I can do to fix it?
