(Applies to: all versions of FusionBB)
Before installing FusionBB for the first time, you should check to make sure that your host meets the needed requirements to run the software. This can be easily done by downloading a .zip file written by FBB Co-Creator and coding guru Dave Lozier.
The file, plus the most up-to-date information related to it, can be found in the FusionBB Pre-Install Check thread at the main FBB site
here.
