[pmwiki-users] cannot acquire lockfile

The message appears when PmWiki is unable to create a wiki.d/.flock file,  
possibly also unable to delete a previously created .flock file. If you have  
such a file, please delete it and try again.

Other things to check are outlined at:


Between 2.2.45 and 46 there is a change in the fixperms() function allowing  
advanced admins to explicitly set permissions on newly uploaded files. I may  
be wrong but I see no difference at all in the treatment of the .flock file.
