"wpf_read_topics" version 1.6.1 WordPress Not Working
I have a problem with "posts", they are marked as unread even though they have been read.
The problem seems to be with the "wpf_read_topics" cookie not being set:
It's not recommended to use the old versions of the plugin. You should always update the plugin to the latest version.
If you still decide to use the wpForo 1.6.1 version, then you should click on the "Mark all read" button located in the forum footer.
