A couple of changes...

First, get the upgrade working.

Second, rename ultimatebb.php and ubbaccel_test.php with .cgi extensions.

Third, edit those two files to include the path to PHP, as noted by your host.

Fourth, set permissions on the files - 755 should do it.

Fifth (phew), visit ubbaccel_test.cgi in your browser, note the output. Make sure that the tests pass.

Sixth (getting there), edit ubb_lib.cgi. There's a line pointing to $vars_config{NonCGIURL}/ultimatebb.php. Change that to point to $vars_config{NonCGIURL}/ultimatebb.cgi

Seventh... turn on the Accelerator, clear the UBB cache, and see if it works. <img src="https://www.ubbcentral.com/boards/images/graemlins/wink.gif" alt="" />

We officially do not advise running the Accelerator using the PHP CGI binary, but if that's all your host has, the above procedure SHOULD work.
