Thread:Project:Support desk/Suddenly no acces anymore

Dear colleagues

I am the owner of the Pollen-Wiki. Today I logged in and wanted to change some words in one of the documents and I got the error message "You do not have permission to access this document". I tried it with several pages: some could be edited, some not, resulting in the same error message. Yesterday everything worked fine. I did not change any settings. I checked the user rights, their ok (755). What can I do? Is the system corrupted by a virus/hacker?

System: MediaWiki 1.19.0 PHP 5.4.4-14+deb7u14 (cgi-fcgi) MySQL 5.5.38-0+wheezy1

Thank your for helping me
