CBSubs - By URL parts regex issue

Hello,

We want to limit access to dtregister registration to active members of two plans (view access is allowed for every one). We only have a few events per year. We solved this in the past by limiting CMS Extensions access using "By URL parts".
Since one of the latest upgrades, the regex does not work anymore (even if your membership is expired, you can register)
We even tried
option=com_dtregister&/.*/&task=individualRegister

The only thing that works is when we use "hardcoded" links (without the regex) Unfortunately the itemid in the second url is user based, so that one only works for my user.

We don't see any warnings in the logfiles.

PHP 7.0.20
Joomla: 3.7.2
CB: 2.1.2
CBSubs: 4.1.0+build.2017.05.19.15.39.30.520d1fe23
CBSubs Content: 4.1.0+build.2017.05.19.15.39.30.520d1fe23
cbpaidsubsbot : 4.0.1

Kind regards,

The regexp usage appears to still be working fine in my tests. Your usages are not valid though. You can not just insert regexp in the middle of a usage as that's not how it works. It only supports regexp for a variable value and only as a whole. I'm not sure how an update of CBSubs could've caused those to not work as they shouldn't have been working to begin with.

In addition to this depending on Itemid to be in the URL is unreliable as Itemid very well could be missing. I do not recommend checking for Itemid and if that's important you may want to use By Menu protection to cover the Itemid case. I recommend the below.

option=com_dtregister&eventId=/[0-9]*/&controller=event&task=/individualRegister(.*)?/
option=com_dtregister&eventid=/[0-9]*/&controller=event&task=/individualregister(.*)?/
option=/com_dtregister(.*)?/&controller=/event(.*)?/
