I never used to have this many page errors prior to installing MT. Plus, look at all the page errors for mt.cgi! Does anyone know what's going on here?

not without knowing what kinds of errors are being generated. presenting us nothing more than a graph showing you have more errors is like taking a car to a mechanic and telling him to fix it because it doesn't go.

you're going to have to be just a little more specific if you want real answers.

This is the only information my web hosting service provides to me about page errors...

unless you can get your host provider to give you more info on the errors being generated, none of us will likely be much more help.

Have you just recently installed MT? Did you have problems with the images showing up at first? Because I'd imagine that would be generating a bunch of 404 errors, for a start... But yeah, what imabug said.
