I have paid a company to host among other things phpwiki for the development team where I work.
I have successfully installed phpwiki in the past and have a database full of entries (from a server we had it running on) to import once it's working but the company that is hosting it for us uses a cluster of machines running CentOS 4.3 (I understand that clusters have a /tmp folder problem because each machine has it's own folder).
The install is having major problems with the /tmp folder even though we are using MySQL which shouldn't need it and redirecting all /tmp entries to a new subdirectory. I have had a long look at it and the people hosting it for us have spent a good deal of time trying to solve the problem to no avail.
 
The problem I'm getting is:
 
Fatal Error:

lib/FileFinder.php:192: Error: /tmp: file not found

Has anyone here had experience of installing phpwiki on a clustered machine and can give me pointers?

Does anyone know why it's trying to find a /tmp folder on a MySQL install in the first place?

Does anyone know of a different wiki program that uses the same database layout so I could just import my phpwiki database into it and have a working wiki?

Thanks,

Karl
