I installed YARRP today for the first time. It worked fine until I changed my relatedness options and built the cache.
The full story: When I first installed the plugin, I the “compute related posts on the fly” box was checked and I did not build the cache. After viewing some posts and tweaking the display options, I changed my relatedness options. This did not change the related posts displayed for the posts I had already viewed but it did change the display for the posts I hadn’t viewed. I presumed this meant that the info in the cache was not being rewritten “on the fly” nor on the occasion of my updated relatedness options. I uninstalled and reinstalled. All my custom options were retained.
I decided to go ahead and build the cache. I got a message “Your related posts cache is now complete. The SQL queries took 0.7 seconds.” However, there are now NO related posts displayed on any of my posts. Further, when I click on “Show cache status”, I’m told that “Your related posts cache is 0% complete.”
So now I have nothing! Any insight into where I’ve gone wrong would be appreciated. Thanks.
