Recently I've experienced on multiple occasions that all links on our site, dolcevita.no behave as feed links. That is, when I hover a link it says http://www.etc in the status bar, but clicking it I'm sent off to feed://www.etc. Also typing in a url like dolcevita.no/toscana behaves the same way - forwarding me to feed://www.dolcevita.no/toscana.
Of course this makes the site inaccessible.
On these occasions I've deactivated plugins a few at the time, but even after all are deactivated, the problem persists. (I've also cleared the cache after each deactivation step.)
Then, just waiting a few minutes, after another reload suddenly the links work as they should. (Its just like there's some cache/ delay on the server - anyway it makes pinpointing the possible culprit.)
Any similar experiences? Possible explanations?
PS Now I've reduced the active plugins to a minimum. Thought I should reactivate them slowly, giving the server time...
