WordPress-Vanillaforums integration with Download monitor WP plugin
A bug is found in the website resulted in users sign up/sign in and try to download some files (managed by download monitor WP plugin) but they get redirected again and again to the login page!
The website is fully integrated between WordPress and Vanillaforums and it was working perfectly for sometime. After updating WP or a plugin, this has started to happen.
The vanillaforums integration plugin is not installed.
