I have a mediawiki set up on an IIS7 server. It was set up as described in the manual. I activated file upload as described here. I think I've got the folder permissions right: modify-read-write for the
IIS_IUSRS group on the
images subdir of the mediawiki install. My
php.ini also allows file uploads.
When I try to upload a png image, I can see a temporary file with a name of
phpF267.tmp being created in a temp folder that is obviously a png file (magic header). However, Mediawiki tells me that it was unable to open the lock file for
mwstore://local-backend/local-public/f/f1/bla.png and does not copy the file. It does not even create the directories
f/f1 in the
Any ideas what might be wrong?
