Have constant errors in log:
[Tue May 21 16:18:32 2013] [error] [client 18.104.22.168] PHP Warning: mkdir(): Permission denied in /var/www/sapi.com.ua/wp-content/plugins/shorten-url/core.class.php on line 794
on every site touch.
Also when trying open plugin settings from WPAdmin console got tons of:
[Tue May 21 15:51:30 2013] [error] [client 22.214.171.124] PHP Warning: readdir() expects parameter 1 to be resource, boolean given in /var/www/sapi.com.ua/wp-content/plugins/shorten-url/core/translation.class.php on line 980, referer: http://www.sapi.com.ua/wp-admin/plugins.php
and log file grows infinitely until free space finished.
Thanks in advance.
PS: last versions of WP and Short URL are installed.
