Ok. I am still having admin issues after getting no help the last time I left it alone and just bore with it for a few weeks.
Today I had an idea, I installed a second blog in a sub directory, I then uploaded to this new blog a back up of my main blogs posts , I then added all plugins and set about configuring them ..
I now have two blogs on the same server, 1 in / , and the other in /devblog/
My new blog in /devblog which has all the same stuff running on it has a fast admin while my main blog in / is like a snail.
The only difference between them is the my main blog has a few sub blogs in it, thats the only difference I can see.
does this mean as it seems to indicate to me that there is a problem with activating the multi blog options ? any ideas on what I should look at to fix this ?
I only have about 4 or 5 member blogs on the main site so its not like there are hundreds or anything.
