Remository

Hello,
I'm migrating a very old Joomla installation with CB + CBSubscription + Remository.
Unfortunately I see that the remository no longer exists.
How can I replace it?

I would like my subscribing users to be able to access folders containing specific PDF files, related to the subscription they choose.

Thanks

I've no idea what Remository is. Are you wanting to protect access to some sort of download manager?

Only way for CBSubs to protect folders that are directly accessed outside of Joomla ecosystem is with CBSubs Folder Access integration.

I don't have to protect directory outside of Joomla ecosystem.

What I need is for my users to be able to access reading PDF depending on the subscription they have subscribed to and when the subscription expires they can't do it
.
I hope I have made myself clear, sorry for my not so good English

That PDF has to be stored somewhere. If they're just directly accessing it in a folder on your domain then only CBSubs Folder Access integration can protect that folder. Ideally you should use some sort of file management extension then you can just protect access to that extension. Suggest checking the JED for an extension for you to put your PDF in first.

You could also use CB Gallery or CB Package Builder to put your PDF in then protect access to either of those. I suppose you could even try to make this work with a file fieldtype and use CBSubs Fields Tabs Protection to protect access to that field then render it on everyone else's profile using a Custom HTML field with substitutions.

Remository was a plugin of Joomla Polis in 2012.
Provided paid access integration between CBSubs plugin and Remository.
How can replicate it?
