Thread:Project:Support desk/Problem With File Upload: Could not acquire lock for "mwstore://local-backend/local-public/1/1e"./reply (6)

I am finding the same problem (except with f/f5 instead of 1/1e), on an installation without superuser access, i.e., the wiki is in a user directory exposed to the web server. Upon upload, under images/ it created three new directories: archive/f/f5/, f/f5/ and lockdir/. All are empty except for two zero-size files in lockdir/. The new directories are owned by the web server's user/group, and I had to chmod 777 the images/ directory to allow this, otherwise the server could not create anything because my user is not even in the same group.

If anyone knows how this is supposed to work, let us know.
