Before you update, please make sure you uninstall any mods that change the following files, or you will be unable to view or edit items in Projectfork:
- administrator/components/com_projectfork/_core/lib/protector.php
- administrator/components/com_projectfork/_core/lib/template.php
The community builder and JomSocial integration are also affected by this patch and a new version is already available.
Now, to clarify how you have to proceed step-by-step:
- Uninstall your mods that are affected (eg. CB integration/JS integration)
- Patch to the latest PF version
- Install the new version of the mods you were using
This is a pure security release and probably the last patch for the Projectfork 2.0.x series. Everyone should make sure to update to this version as soon as possible.
