For the last few days I have been getting a security warning when i access the photography forum. It says that there is a problem with this sites security certificate.

Hi there

That sounds a bit odd, can you please upload or send me a screenshot showing the error?

thanks

I don't get any warning, or any other message.

Might be worth checking the date and time settings on your device.
Had a similar problem a while back due to the date and time on my tablet being completely off.

Hi Steve,
Strange as it may seem the problem looks like it was caused by the bookmark on my tablet.
I tried typing in the web address and did not have a problem so I removed the bookmark put in a new one and it seems to have fixed the problem.
Cheers Frank.
