forum unread vs Opera 12.17

[#1]

I see loads of unread posts when viewing the main forum and checking each sub section, but if I use http://community.plus.net/forum/index.php?action=unread at times it returns none.  The attachment is from just now, but clicking unread it gives me no threads

[#2]

That is probably the intended behaviour. There are two different lists of unread posts.

• Recent Unread Topics / unread posts since last visit - can be empty even though there are unread posts on the boards


• All Unread Topics

[#3]

Just to expand on what ejs said a little:
When you click UNREAD POSTS it goes to http://community.plus.net/forum/index.php?action=unread. The title on that page is Recent Unread Topics. At the right above the list of posts is a link All Unread Topics which goes to https://community.plus.net/forum/index.php?action=unread;all;start=0.
Something else you might not be aware of:
Clicking on the forum list gives you the recent unread topics in the forum. There's then a All Unread Topics within the forum link at the top right.
Clicking the little icon beside the title of a topic takes you to the first unread post within the topic.

Then fault of the main link on the forum, even its tooltip says it should be the other link

[#5]

The tooltip is correct - it is unread posts since last visit.
Note that visit will be a browser session, it may need you to fully close the browser, not just go to other web pages or close the tab.
