Pair Networks recently updated their servers. I’m seeing PHP version 5.3.18 and MySQL version 5.0.91. I have a link to a currently-empty (no posts) tag. On that page I’m receiving a warning from slim stat:
Warning: array_pop() expects parameter 1 to be array, boolean given in /usr/www/users/jlove/diskclock/wp/wp-content/plugins/wp-slimstat/wp-slimstat.php on line 223
thank you for pointing this out, it’s definitely a bug. I will fix it asap, sorry for the inconvenience. In the meanwhile, you may have to disable WP SlimStat or turn off warning messages in PHP, to hide that error you get.
