I’m having the same issue as item #1 above. It’s a brand new blog with only a couple test posts though. Using WP 2.8.4.
Warning: addslashes() expects parameter 1 to be string, array given in C:\Users\Adam\Sites\apb\wp-content\plugins\yet-another-related-posts-plugin\options.php on line 77
Plugin does seems to be working properly though, is this not a cause for concern? Thanks!
