I saw a series of strange error messages on my site home page this evening after I had updated to version 1.4.3 of Kcite. Also I saw similar error messages when I tried to log in to the dashboard. I promptly raised a support ticket with Tsohost. Darren on the helpdesk (who is a star!) soon had a solution:
>You had the character 'w' in front of the first PHP line in
/home/departuo/public_html/wp-content/plugins/kcite/kcite.php
>Hence the error. I've removed this for you, and the site appears to be OK now.
I have tried to contact the developers, but their site (http://knowledgeblog.org) appears to be down.
