Waiting for Blog plug In to Provide Page issue

Hi,

I have several webs using Rapid Weaver 8.1.7 and one of them has suddenly stopped uploading to the web and it gives me the Waiting for blog plug in to provide page message then does nothing. The upload box disappears.

I do not have the problem with any of the other webs using the same server, coming from the same disk. Any idea how I can fix this?
