I met this situation before (I am currently using manjaro + firefox with no extention) and after reloading the page multiple times it just gone
Use vpn
How do you expect that to work?
Same here. I am using windows + chrome and the same problem just happened recently.
Maybe we should call Mike Mirzayanov for that?
Codeforces uses the Mathjax library to format mathematical equations, and if you view network traffic on your browser, you will see that when trying to get the Mathjax library it is not getting anything back :(. So mathjax library is not being loaded.
Also, I have found a fix. Visit https:// cdn-mathjax dot codeforces dot com/MathJax.js?config=TeX-AMS_HTML-full and then reload your codeforces tab and it should fix it, it worked for me.
What the hell dude! how did that worked? Anyways thanks!
First step to finding solutions like this is to open developer tools in the browser and looking for errors in the console.
My browser blocked that page saying intruders tryna steal your data :)
Yes, that is because the ssl for cdn-mathjax dot codeforces dot com has expired, so your browser thinks that it is unsafe, and you have to tell your browser that you trust it (Usually by clicking "proceed").
Hello, I'm not able to open this site, and I get
Failed to load resource: net::ERR_CONNECTION_TIMED_OUTfor Mathjax.js on my console. Anyone experienced this? Any help please?Even I have been experiencing Mathjax issue since this morning and the solution provided here is not working...
Is it OK now?
Yes sir, now it is working fine... Thank you very much for the instant resolution
https://cdn-mathjax.codeforces.com/MathJax.js?config=TeX-AMS_HTML-full go to this url
It is fixed now.
The same as.
This problem seems now happening again caused by the SSL certificate not matching with the host name
oh, so i am not alone.
