Thread:Extension talk:VisualEditor/Session ends after some idle time and cant save

so it seems to happen that when i edit a page and idle in the editor while doing some research after a period of time (20-30mins) i cant save the proress anymore and it loggs me out... it seems to be a specific problem with the editor cuz i dont get timeout on the normal wiki - the token in the php ini file is also set to 0 so it shouldnt happen. anyone an idea?
