I am having a very frustrating problem, no matter what seo plugin I install on my site, it won't work, ie nothing will update when I enter details in the seo edit section and save. I get a 'sorry, page not found' error, when I try to do this.
This is the same for all the seo plugins I have tried - Yet I have other sites on the same server, running exactly the same WP theme and the seo plugins work fine with them.
I can't figure out why it is just one site, which won't allow seo plugins to work. Is this a server issue? Or what could be causing this seo plugin problem on just one WP site on my server.
all advice appreciated., thanks
