# help needed for a latex and posting problem?

when i write the question in between  signs and use latex format for the math expressions I face a weird problem.

after posting the question when i check it i don't see them in the correct format. I mean I just see the dollar signs and everything as it is written. Plus when i read others post I see them as it is too.

wierd thing is, when check the same question from my android phone everything is normal as it should be? why do you think this happens? it it somthing about my web browser? I have just updated the browser and the problem is still there? need help on this?

I added the screenshot of how I see an answer as follows: It is seen in different and normal when I check it from my android phone.

Further information:

• Javascript is enabled and no known ad blockers are active
• Google Chrome on a Windows Desktop is used, it works using Chrome on android (except for showing my user image), the problem can be reproduced with other browser, e.g. Firefox as well.
• The phone and the desktop use different networks / internet connections.
• The issue is not localised to Crypto.SE but applies to all LaTeX enabled SE sites
• The problem persisted for more than 1 year
• Chrome's dev console shows errors fetching the imgur images and the MathJax JS, picture here. Similar errors can be found here and here.
• I can't access cdnjs.cloudflare.com nor i.stack.imgur.com (by clicking, the latter only works when HTTPS -> HTTP redirects are allowed in your browser)
• The MathJax problem disappears when the desktop is connected to the phone and the phone network is used.
• Sorry to say so but I could not replicate the problem using Google Chrome… unless when using an extention which blocks specific requests (like an ad blocker does). Also, deactivating JS causes an alike hickup… but that doesn't explain why your profile pic doesn't show. Personally, I am also using Chrome on my laptop and block a small truckload of things — but MathJax works for me nevertheless. Therefore I doubt it's a Chrome problem. Sorry I can't help here. Maybe someone else has an idea? I'll add a "featured" tag to the Q so it remains in focus for others to discover. – e-sushi Aug 23 '18 at 11:18
• I am also having JavaScript issues on all SE sites as well as other sites such as Facebook; this seems to be a localised issue, hopefully temporary. – fkraiem Aug 23 '18 at 14:37
• @fkraiem my problem is there for a long time? a year or more may be... so i dont think it is a temproray situation. i think site managers should adress this problem more seriously. hope they find a solution soon. – esra Aug 23 '18 at 21:37
• @e-sushi , thanks for your efforts. I have detected one more problem as well. while i am commenting the automated names after @ button does not appear in the Cryptography site ( not here the Cryptography meta) Here it comes automatically with no problem. these are all really weird though:/ – esra Aug 23 '18 at 21:41
• @IlmariKaronen given that you have a lot of experience with Meta.SE and this particular problem isn't specific to Crypto.SE, do you think this request should be migrated to Meta.SE? – SEJPM Aug 24 '18 at 12:18
• @SEJPM: Maybe, but it would be useful to have some idea of what's going wrong first. Without some idea of what's causing this issue or some way to reproduce it, I don't think meta.SE can do anything more about it than we can. (Also, it's not strictly necessary; AFAIK, the SE devs to monitor bug reports on all metas, so as long as we add the bug tag they should see this. But again, they'll probably also need more information to do anything about it.) – Ilmari Karonen Aug 24 '18 at 13:35
• Well, those errors definitely mean that your browser failed to load the MathJax.js file (and a bunch of images as well). Just from looking at the screenshot, I can't really tell why, though. If you don't have an ad blocker or some overzealous personal firewall installed, my next guess would be filtering by your ISP. – Ilmari Karonen Aug 25 '18 at 12:46
• From your screenshots, I'm guessing you live in Turkey. Apparently, at least imgur (which Stack Exchange uses for image hosting) has been blocked in Turkey for quite some time. I'm not sure about CDNJS, however; they're hosted by CloudFlare, which has had occasional issues in Turkey, but at least with a bit of Googling I couldn't find anything about it currently being blocked. – Ilmari Karonen Aug 25 '18 at 13:56
• @IlmariKaronen thanks. it seems that we cant solve the imgur problem then but i think the mathjax problem is still there without an answer? – esra Aug 25 '18 at 14:22
• @SEJPM i think mathjax problem is definitely related to the network i used. but i wonder, why it works in one network and not another? my home local network does not support it as it seems. for the i.stack.imgur.com it says the site is not reached. – esra Aug 25 '18 at 15:53
• @esra Are your phone and desktop networks connected to different ISPs? If so this may cause the issue because the one ISP may block cloudflare while the other one doesn't. – SEJPM Aug 25 '18 at 17:00
• @SEJPM yes the isp 's are different firms. i think i should contact with the isp then. Thanks a lot. you helped a lot i am not sure if they can solve it or not though but i will try – esra Aug 25 '18 at 17:26
• Updates? One simple thing to try is access your edits from another machine elsewhere, like at your mate's. – Paul Uszak Sep 20 '18 at 22:55
