Unable to update content or enable / disable module via Drupal Admin once migrate to live server I have moved my website from local machine to live server, but after migration I can not save or update contents. After clicking on 'Save' button page refreshes without any changes. Also I can not enable or disable the drupal modules, and there aren't any errors displayed. Please help me out in this and do let me know solution in isolating this issue.
problem was server firewall called mod_security. It's purpose is to stop hackers from inserting mysql_query type commands into your website. So, I solved this problem by disabling the mod_security service.
