If all is good now, please consider marking the product as installed. :)

I can not understand why a guest can go to the page mystarpost.php when he is not even registered on the forum

Update - Version 1.6.1:

• Guests shown no permission message if trying to access the external script.

If you update to version 1.6.1 you'll have to redo the hacks to the external script. :)

Thank you very much! Thank you for giving so much time to my problem.
How can I ban this mod for some user groups?
What would forbidden groups displayed the page as well as guests.

Update - Version 1.6.2:

• Users not part of the allowed usergroups shown no permission message if trying to access the external script.

There is a setting that allows you to set which usergroups are allowed to use this product. Now they will get a no permission page if they manually enter the url to the script. :)

True, they can not do this by reference. But they can go to /mystarpost.php

https://vborg.vbsupport.ru/external/2017/04/9.jpg

And when they click on "Remove" there is a database error

With version 1.6.2, they will get the no permission page if they are not a member of one or more of the allowed usergroups. Users who are allowed but don't have any posts in their list cannot remove anything, because they are unable to select anything.

What do I need to do with version 1.6.2?

If you want to show users not in the allowed groups the no permission page, then you need to update to this version, and apply the hacks to the external script mentioned before.

We just had a member asking for some sort of bookmarking threads feature and I came here to do a search and there it was! :)

Working perfectly out of the box on vB 4.2.4
