Hi, I am using Drupal 6 when I relogin after restarting the server Some of the module behaviors have suddenly changed like

1. onClick of configure link on any block I am redirected to the same page

Like when I click on : ?q=admin/build/block/configure/block/3

I am redirected to : ?q=admin/build/block

2. onClick of Administrator >> site building >> views I get a page with views data

but all the tabs on top of it are missing like add/edit etc

My login in the administrator login

1. I have checked Administrator >> user Management >> Permissions there is no

Change in that every permission seems to be their(though I am admin)

2. Browser caching is also not their
