I am running Drupal 6 and my site has been up and running for many years.
I am facing this problem for many years and I don't bother to fix it until now when my productivity on managing the site has decreased due to this problem.
The problem is when I am editing the user when I am logged in as admin, the loading take forever if not hang or display cannot find error message to load the user page.
I seriously have no idea why is this happening, all other pages are loading fine. The only pages which are not loading fine is the edit user page when I am logged in as admin.
Any help please?
