Mollom has stopped protecting forms on my site www.ansn.edu.au.
I upgraded to 7.2.4 and I'm getting this error.
The server time of this site is incorrect. The time of the operating system is not synchronized with the Coordinated Universal Time (UTC), which prevents a successful authentication with Mollom. The maximum allowed offset is 5 minutes. Please consult your hosting provider or server operator to correct the server time.
I'm guessing this is the problem, can anyone tell me how to fix the server? It's a VPS running plesk.
I'd love some help with this, I had 500 spam user registrations over the weekend.
Thanks in advance.
