Just a note - if like me you upgraded to 4.3.1 without uninstalling Actions Permissions first...
I got a nasty note on the Status report and when running update.php after upgrading - oops.
I tried to downgrade back to 4.2.7 and that completely broke my site. Super oops.
After many upgrade/downgrade/uninstall/reinstalls... I found a way to re-add the actions_permissions module so I could uninstall it after the fact. I'm surprised it worked... but it did!
I downloaded the 4.2.7 tar file, and from within modules folder I grabbed the actions_permissions module folder and dropped it in to the current install (via sftp) - this allowed it to be displayed under Extend > Uninstall and I was able to use that mechanism to uninstall "Actions Permissions" properly.
And then, hooray! The nasty note went away on Status report and update.php - All is well and good... except of course I have no actions permissions :-/
Boooooo.
