I think the answer is that it is not a "connection problem"...

The css validation of local files (Document > Validate CSS) consistently has not worked for me in version 14 and - if memory serves me right - in version 12. The error messages have varied somewhat, but most commonly I've experienced the lockup described in this thread and in the prior one that Gunsmoke gave a link to.

I found the answer given to one poster's support topic in the previous thread "...it is caused by Windows very strict security settings..." a bit odd, but I took it at face value and went the route of going straight to the CSS Validation web site for my validations.

For what it's worth, this is what I get from the HTML validation:
http://validator.w3.org/check?uri=http% … mp;group=0
and this from the CSS validation:
http://jigsaw.w3.org/css-validator/vali … mp;lang=en

To be clear, both of the above were obtained directly from the validator websites and thereby totally unrelated to Coffeecup.
Quite a number of things to take a look at, in addition to the parsing errors...

Of course I will Steve Im not at the laptop right now but later Ill try see if I can validate pun intended lol your findings

Thanks for that Per its great to have you folks given feedback

Mine will work most times. It usually fails when it takes a little longer.

Yeah Steve tried the site you mention and I've attached the results what I get, which is basically the same as you and it wanted to close the program down

Yeah it's very strange Eric, I can't get the CSS validation to work at all but I downloaded the trial version of V14 and that seems to work?? Any ideas? I think Per said that there were problems with both and there maybe, definitely with V12 I've tried shutting down the laptop and all the usual things but nothing seems to work
