  • Staff List

Website, Documentation, Support


  • PHP >= to 5.3 - 5.6
  • MySQL >= 4 - 5.6
  • Web server -- usually Apache, but some people have SubjectsPlus running on IIS
  • JavaScript enabled for the admin to work properly.

If you run into any missing/weird functionality, check that the following extensions are enabled for PHP:

  • cURL
  • MySQL
  • mbstring (not necessary, but you'll need to tweak header.php without this)
  • simplexml (for reading RSS feeds)
  • json (some data is stored as json)
  • gettext (only if you need internationalization, aka translations)
  • gd (image resizing--notably for headshots and generation of video thumbnails)

If you have MySQL 5.7 you must disable ONLY_FULL_GROUP_BY permanently. Please refer to this stack overflow issue.
