I apologigize for the question, as it sounds silly. But I am forced to ask this question, as I didn't find it's answer anywhere.
I have about 3 sites on WordPress, and 2 are working absolutely fine. But the 3rd one have some problem with links.
I mean, If I go to All Plugins page, and click on Activate or Deactivate or Delete, then nothing happens.
However if I copy the URL by mouse right clicking (and copying url), and visit after pasting it in browser, then it works properly.
I have WordPress 3.5.1 with theme twenty twelve on all sites. I have also tried changing theme and removing all plugins, but still the problem exists.
Can someone knows the resolution of this issue.
