This is an intermittent problem but of the four web sites on my hosting account I know that I am getting these intermittent errors on 3 of them. I am active on two of the four sites by not on the third one which makes me think that it is a problem with my host. I did call them last week but their testing tells them that all is OK with my package. I am not so sure about that and will be back on the phone this week to follow up.
This is a difficult problem to track down because it is intermittent. I have tried backtracking on some of the plugins I recently installed but it has not made any difference.
Anyone had any experience with a problem like this?
