Advanced panel gives an error message - Anybody else has this?

[Atheist Universe]

For some reason, today I can't change anything to our CSS in the Design Studio Advanced panel. I get an error message when I want to Preview. Even without making any change: just opening the panel and clicking on Preview gives an error.

And it's not a browser issue as it happens in Chrome, Safari and Firefox. The error messages are different in each browser but they all pertain to an undefined url.

It began on Friday, then for a while yesterday, it was working fine but I did not make any change to either LESS or CSS, now it's broken again.

I filed a support ticket.

Anybody else is having this problem?

We can NOT make EDIT changes in our TEST network using IE but we can change CSS. in Advanced 

Using Chrome it all works---it's like working in a circus!

Still happening today & no response yet from support. We're tweaking our front page design and no access to CSS is definitely a show-stopper.

Why me???

Maybe Ganesha does not like you today, but this happened to me in the past and I went and used Internet Explorer or Opera to get around the issue.  I was only using the Advanced Tab and not the full LESS variables as you are doing.

Not doing anything with either LESS or CSS: just opening the Advanced panel and hitting Preview gives me an error message.

It's not just Ganesha, it's the entire cohort!

This just came in from a member, silly girl sent us a Fraud under report a ticket which Really worried me only to find it was simply more Ning issues sheesh. Anyway this is what she said is now occurring although I don't see a problem myself but often members don't say anything so I have to wonder what is happening on their end:

When I'm in Pagan Underworld, My screen looks as though it's jumping up and down (seems to be a prob. with bottom bar): Also, visual of typinglagging far behind input of typing). Started yesterday. THX!

The plot thickens:

• Now more than a week without being able to use the Advanced panel in Developer Mode.

I was asked by support to remove all my customized CSS - revert to the theme defaults - and add each item back one by one to figure out which one is faulty. A colleague  'suspected' faulty CSS.

We have dozens and dozens of mods!

Before I'd do that, I replied that:

• it was intermittent, that with the same CSS and LESS I was sometimes able to hit Preview without an error, but most of the time was prevented.
• one of our admins reported the same problem in all his browsers except in Opera, where the Advanced panel functioned consistently
• it worked flawlessly on the test network in all browsers, with the exact same CSS, LESS and Custom Code.

How could it be faulty CSS?

I asked that the case be escalated.
No response yet.
