My site has just been transferred to another hosting company. Everything worked fine using my past host (VPS) but since I am now transferred to my new host (VPS) I keep getting an intermittent problem which stops users logging into the site. I have the hosting company looking into this but nothing has been found so far. I wondered if anyone have experienced this before or could advise me. I am running the latest version 1.8. like I said it only happens now and again and what happens is you try to login into your account which times out then you end up with a server 500 message.

After awhile the site then recovers and everything goes back to normal.

Thanks
