Unable to save JomSocial Configuration

Symptoms

  1. Upon saving the JomSocial Configuration, you are redirected to the Joomla Administrator Control Panel.
  2. Any changes done in JomSocial Configuration are not saved.

Possible Causes

Suhosin Module

Suhosin is a module installed in your webserver to strengthen its security against common attacks. A misconfiguration or severely strict security restriction in Suhosin could easily prevent PHP scripts from saving information into the database. You can verify the existence of Suhosin by going to:

  • Joomla 1.5: Administrator > Help > System Information > PHP Information
  • Joomla 1.7: Administrator > Site > System Information > PHP Information

and locate:

  • "This server is protected with the Suhosin Patch 0.9.6.2"

To solve this issue, please modify the PHP.ini, to increase the value of these two (2) settings:

suhosin.post.max_vars = 1000
suhosin.request.max_vars = 1000
