Ok I've seen a little about this in the forums but nothing helpful. I've MT v 2.661, using the default installation.

I suddenly cant login anymore as i'm informed i dont exist anymore(so thus i cant retrieve my username either).

Also I notice when i click on the comment button in my blog an error message appears in the popup

'An error occurred:

Invalid entry ID '36''

Mt-medic doesnt work, it doesnt even mention authors or blogs exist in the MT folder.

what to do?


this is my mt-check output for db info

The host i use uses a windows system, i know there may be the possibility of the DB server version having chnaged how do i find this out please, or if anybody has other ideas?

This definitely sounds like a change in Berkeley version - you'd need to ask your host about it, and the solution is same as the last item in the Troubleshooting Manual ("I changed hosts and now I can't login to Movable Type").
