I am running Drupal 6.13 on my linux server (it meets system requirement, php5, mysql5). Just recently, i cannot save ANY changes in permission on my website. When i want to give my authenticated users a feature, such as the "search" module, i check the box and save the permissions, however the changes are NOT reflected. There isnt even a response from Drupal saying that the changes were saved. The page just reloads and the settings were reverted.
I'm not sure what the issue is, can someone help direct me towards a solution please?
