In the Phorum settings, there is an entry called "Cache Directory".
On Windows systems, the installer will have set that to the default
C:\Windows\Temp. The cache directory
is used for storing cached data and compiled templates. You can
change the location of your cache directory if you do not want the
Phorum files to be in
or if you see the following kind of error message:
Warning: fopen(c:\windows\temp\tpl-default-header-a72fb9dd20915e5953aa9b07d3eb3871.php): failed to open stream: permission denied in c:\path\to\phorum\include\templates.php on line 184
In that case, you will have to change the cache directory
setting to point to a valid location. We advise you to change
./cache (this directory is already
in the Phorum directory). Make sure that the webserver can
write files to this directory.
