Specs in signature.

This morning I added a topic and then changed my text editor and received this message when I went back to the forums index.

I then tried accessing the page again and it worked. I then re-indexed the tables and now it's not loading up at all.

The rest of DNN loads just fine, but the YAF does not. It just says "Connecting" and nothing further happens.

I logged into the host control panel for the site and did a backup of the database.

Then stopped and started my site.

Got the same same page won't load error type message.

Did nothing, but tried again and now it's working.

Any ideas what happened here? Should I blame this on my web host and punch them in the ding ding?
