Thanks for the suggestion Michael.
I had this Option off all the time. No joy there.
Looks very interesting. Jetpack are saying its not their problem, also.
I have deleted and re-installed both plugins. I have re-installed the latest of WordPress, I have de-activated every other plugin, one by one and the same issue is occurring only with Contact Form DB. I don't know what else to do.
Then I read this page - which is very interesting in itself.
However even that doesn't solve my issue.
Are you able to suggest anything else Michael? We're talking about a website that's in production all the time and cannot be taken down for long periods of time.
Here are the systems settings -
System Settings
System Linux host 2.6.32-20130307.60.9.bh6.x86_64 #1 SMP Thu Mar 7 15:58:33 EST 2013 x86_64
PHP Version 5.2.17
MySQL Version 5.5.30-log
The other thing I should be doing is paying to get the full features of Contact Form DB and I want to know how much I need to Donate in order to buy your wonderful product. Where do I find this information?
