What this add-on does...
The add-on displays a counter above the "What's New?" link on the navigation bar.
This counter displays the current number of unread posts (individual posts, not threads) that are visible to the user (it counts the number of unread posts in the forums that are visible to the current user on the forum list).
The counter is only shown to logged in visitors.
If you wish to install this add-on on XenForo 1.1.x then you must use this version of the add-on.
HOW TO INSTALL
The easiest way to install this add-on is if you use the Add-On Installer.
Download the zip file.
Extract its contents to your hard drive.
Upload the contents of the upload folder to the root of your XenForo installation.
Complete install via the Admin CP using the provided XML file.
IMPORTANT INSTALL NOTE
Something very important happens during the install or upgrade of the add-on.
An index is added to the xf_post table. This index applies to the post_date column.
Adding an index can sometimes be a lengthy operation (directly dependent on the number of posts in the xf_post table). On my forum with 3,000,000 posts the operation took 50 seconds.
Often this amount of time is beyond the PHP max execution time.
If you receive an error during install or upgrade stating that the max execution time has been exceeded, then please run the following query directly on your XenForo MySQL database using PHP My Admin (or preferably directly on the command line):
After that query has run, the add-on will install/upgrade without issue.Code:ALTER TABLE `xf_post` ADD INDEX `unread_post_count_post_date` (`post_date` ASC)
In the event that you're unable to perform this query and as a result performance problems persist then you should uninstall the add-on as no further support can be provided.
