ABPro 4.0.5 is required for Joomla 4. 

Features that not are coming over to Joomla 4:

  • Payment processors, other than PayPal.
  • Email Marketing (MailChimp, AcyMailing)



Known Issues:

Reminder modules do not work with Joomla 4.

The ABPro reminder modules are simple php files run by the cron job.
The mechanism that ABPro reminder modules use to instantiate the Joomla framework no longer works.
This may be a security issue. (??)

I have no fix for it at this time.

Moving to Joomla 4 / ABPro 4.0.5

As table changes were required for Joomla 4, you cannot simply install ABPro 4.0.5 over top of 4.0.3, you need to:

  1. ABPro Backup under J3, ABPro 4.0.3
  2. Uninstall ABPro 4.0.3
  3. Upgrade J3 to J4
  4. Install ABPro 4.0.5
  5. Restore the backup from step 1 with ABPro Restore
