Question What is, clean user cache?

When Joomla user is upgraded with additional permission, in Kunene nothing happens until I use “clean user cache”.
I am using subscription plug and would like promoted user gets an instant access.
I am wondering which cache is it, does it expire at some time where the time can be changed?

Is it possible to have “clean user cache” automatically run every few hours ?

You should not need to use the Synchronize Users (Clean User Cache) function very often. Significant improvements were introduced in K 1.7.2 to overcome the problem that you referred to in your first post. The function is sometimes needed if you change a user's Joomla permissions while they are still logged-in to your forum. Joomla permissions are only queried at the time a user logs in. If you clear the user cache then this will force a requery of those permissions if the user is still logged-in. Otherwise, when the user logs out, the permissions will be requeried the next time that user logs in.

It is latest kunena version.

The point is, it should be an automated subscription but user promotion changes in kunena only when “Synchronize Users” is applied.”

Since the user is subscribing of course he is logged in when his status changes.

I am looking for solution how it can be an automated subscription. When user subscribes he should get instant access or at least it can be after few hours.

The way it is, he will get an access only when I manually activate it.

If the subscription plugin modifies Joomla permissions on-the-fly and if some of your forum categories are restricted via Joomla permissions then I can understand how the issue may affect your circumstances.

It would seem that another plugin needs to be written, triggered by the plugin that modifies Joomla permissions on-the-fly, that clears the Kunena user cache. So it would seem. Would you agree?

I don't have a technical solution in mind. Perhaps another member of the community could help us with this question.

Yes.

Akeeba subscription has a plugin to upgrade joomla subscribed user.

Perhaps if kunena code to sinc users is inserted there, it might work.

I would try to add it if I know which code.
