Hi, my site has started to show this warning when the full domain http://www.bayvetgroup.co.uk is typed in. Warning: mysql_num_fields() expects parameter 1 to be resource, boolean given in /home/ourvetsite/public_html/wp-includes/wp-db.php on line 3026. If you then refresh the page it loads normally. If you type bayvetgroup.co.uk the message is permanent.
this error started when I deleted some plugins that I no longer use and updated ot the latest edition of wordpress. I have updated all plugins and tried general troubleshooting. Other sites using the same theme on my multisite install seem to be fine at the moment
Any ideas/thoughts please?
Thanks
Chris
