LinkedIn is showing as a blank page with a mostly blank navbar

Unread post by BrokenEye » 2021-07-10, 04:05

As far as I know, this started in the most recent version of Pale Moon (until recently I didn't visit the site very often). Whenever I go to LinkedIn, no matter what page I go to, it loads as only a blank off-white page with a navbar, but the only button on the navbar is the "home" button, the one with the LinkedIn logo on it (which still works, though the page it sends you to has the same error, so it's not exactly helpful). Naturally this renders the site totally unusable. What's worse, I can't report it to LinkedIn's tech support, because their support page is a page on LinkedIn, and so the error happens there too. The only difference is what it says in the address bar.

Turning off AdBlock and my VPN have no effect. Disabling plugins has no effect. The problem occurs on both computers I own, which run different versions of Windows. LinkedIn still works on other browsers but, you know, I'm trying to limit my active logins.

Here's the web console stuff they told me to include:
Content Security Policy: Directive ‘child-src’ has been deprecated. Please use directive ‘worker-src’ to control workers, or directive ‘frame-src’ to control frames respectively.

It's the problem with relying on JS to render page content and not making it robust enough.
The issue seems to be the following line:

Code: Select all

SyntaxError: invalid regexp group
Which would mean they rely on a specific extension to regular expressions introduced by Google.

Unfortunately since all their scripting is minified and obfuscated there's no definitive info about why the page doesn't render, just that that is the most likely problem, and I don't think LinkedIn has any interest targeting browser engines other than Blink (Chrome/Edge/Brave/Opera/etc.)

We have an open issue to get this in, but so far very little progress as adapting Blink's regular expression parser to our use is proving very problematic.

LinkedIn appears to work for me on Linux.

Just checked and it does seem to work for me too (for what I can see without an account anyway).
Did you mess with the user-agent, perhaps?

I've just taken a look and it seems that the site is partly broken.

Go direct to a random job advert - https://www.linkedin.com/jobs/view/2645581989/ - and I get the blank page reported by BrokenEye.
The main page is fine, and I can login - but if I do then the main navbar is also blank, as reported.

I last logged on a few weeks ago when it was OK, so there must have been a recent change.

Well, feel free to report it to them but since they consider themselves "too big to be in error" don't expect them to make any changes.

I don't know what that means, so probably not.

I don't get a blank page as reported, but it does seem to have big white spaces and doesn't have clear navigation so i guess it is missing a few things (unless those are big-ass ads).

As an aside, got to love that tight integration with Google now; see the "Oh just click this button to have all data Google has shared with us" pop-in, that somehow already knows who I am while I'm unknown to linkedIn ;P)

Neither do I, today - I'm now seeing the same as you. Guess something's changed again.

Well it must have been going back and forth then? It hasn't been a problem when I first checked after the OP reported, and again 2 times after now. I haven't seen the problem so far.

I can see 'invalid regexp group' among other errors when opening the home page so that's one data point.

It is obvious that Microsoft is continuing to assimilate LinkedIn and implanting it with more Google Technology that never needed to previously exist for a highly successful service and only works within the Chrome Collective. Just like they are doing to Github, have done to skype, did to hotmail and everything else they have bought and corrupted.

WebComponents are next, I am sure. Sure is funny how all these sites always pick the bits WE don't have and are having trouble getting or don't want. The same several things.. Insane regex, Insane Dynamic ESModules, Deprecated Window.event, Worthless PerformanceObserver, Retarded WebComponents, Monopolistic Widevine DRM, and Ridiculous WebRTC...
I'm sorry, my responses are limited. You must ask the right questions.

Now I'm getting a blank page on my Windows 10 computer but not on my Windows 7 computer. It's progress, and the site is no longer totally unusable, but... what the heck?

Complain to LinkedIn about your browsing experience, please. They are clearly messing with their site code in a detrimental way.
