quick reply suspends on white page

This just started happening a few days ago on one of my forums. It is the one I post on most frequently, so I don't know if it is happening on the others or not.

Anyhow, this is what is happening. Don't know if it is a vbseo thing, an ajax thing, or what.

When I submit a quick reply, the pages will reload sometimes. When it does this, it just sits suspended on a blank white page until I hit refresh.

Could this be an issue with ajax?

Hello Michael,

is it happening if you temporarily disable vBSEO?

I cleared the cache for that site and so far it hasn't started again. If it continues I will disable and see if it continues
