I've changed two cookie settings which should hopefully solve the problem.
The new version of the forum had an additional cookie (enabled by default) which prevented cookie stealing by embedding IP-Location related info. I've disabled this as I don't believe we need the super security.
Thanks for that Woody, no I hadn't seen the thread, I added the CCleaner.com cookie closed CCleaner then revisited and didn't have to log in so, hopefully it's worked.
adding the CCleaner.com cookie had appeared to fix the problem,however today I have had to log in again.
Same here, hopefully that was just the cookie settings change. I have been kept logged in with just the CCleaner.com cookie for last week, no forum cookie was appearing, but that returned today too.
CCleaner.com cookie has been removed, forum.CCleaner.com should be the only one appearing now.
I don't know if this is a forum setting or not. But the password part of the cookie, expires 7 days after the time you logged in. That's probably why it's only happening ever now and then.
No probs with the auto login but where I have found a prob is when I add an attachment into a post, press the "preview" button then try to have a look at the attachment I get the below error message:
"Sorry, an error occurred. If you are unsure on how to use a feature, or don't know why you got this error message, try looking through the help files for more information.
The error returned was:
Sorry, but you do not have permission to use this feature. If you are not logged in, you may do so using the form below if available."
