I just upgrade my service provider from apache to litespeed webserver and Civicrm stop to work.
The error is in a lot of page:
Sorry but we are not able to provide this at the moment.

That is seems related to the url base configuration, but it is the same of before and it worked perfectly. I had a similar problem when used Varnish cache that solved removing that cache. But now the pages are no cached with litespeed. I cannnot also configure the backend in order to set civicrm in debug mode. Have any suggestion in order to check if the problem is related to litespeed?
Example page of error: http://www.grag.org/civicrm/?page=CiviCRM&q=civicrm/profile/create&gid=16&reset=1
Here is a hint of the problem: if I use a demo site: http://wpmaster.demo.civicrm.org/wp-login.php (user demo/demo) and then the link http://wpmaster.demo.civicrm.org/wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fmember%2Fsearch&reset=1 using the search button I have in the query string the following http://wpmaster.demo.civicrm.org/wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fmember%2Fsearch&_qf_Search_display=true&qfKey=6709b858d58d2f669a89cae4c9d06171_4657
but on my site after the http://www.grag.org/wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fmember%2Fsearch&reset=1 pressing the searrch button I have the following link and the error http://www.grag.org/wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fmember%2Fsearch the variables is missing.
Now it is solved thank to the service provider that modified the server configuration
