For some time now, trouble occurs when editing answers and comments. The automatic spell checking no longer works properly. For example, below is a screen copy of what appears when I am typing. Many words are underlined even without spelling mistakes:

One suggested that the trouble might come from the browser (Internet explorer). But I don't know how to fix it.

Also, I observed that the trouble appeared just after recent navigation bar change.

Could this be causing the problem?

• Have you tried a different browser? – user222031 Nov 6 '17 at 8:11
• I tried. But then, I cannot login to MathStackExchange. It says "e-mail or password incorrect". I prefer continue with Windows Explorer and fix it if possible for the edition on MathStackExchange. It correctly works for years. – JJacquelin Nov 6 '17 at 8:41
• Could it be that your spellchecker checks for a language other than English? – Michael Greinecker Nov 6 '17 at 8:59
• The standard first thing to try for any computer problems is to restart the machine to see whether the problem goes away. – Gerry Myerson Nov 6 '17 at 9:04
• This seems as a question asking how to user browser and not the question related to this site. Could questions like this be on-topic on SuperUser? I am not familiar with that site well enough to judge this. (They have spell-check tag. It might be worth checking among those question whether your problem isn't already answered there.) – Martin Sleziak Nov 6 '17 at 9:20
• I switched my spell checker to a different language and I get a similar output. Is this happening only on MSE? If it isn't then this might be relevant: superuser.com/questions/480540/… – user222031 Nov 6 '17 at 9:20
• Finally, this was a problem of browser. I found how to access to the language options. I wonder why they were deactivated. After reactivating the English module, the spell checker works correctly again. So the problem is solved. Thanks you to everyone who answered. – JJacquelin Nov 6 '17 at 10:10
• I don't really see how this is a problem with the site and not with your spellchecker... – Asaf Karagila Nov 6 '17 at 12:39
• @ Asal Karaglila : The conclusion is that was not a problem of the site and that was a problem of the spellchecker of the browser. For me, this was not a-priori obvious. The above comments allowed me to get to the conclusion. – JJacquelin Nov 6 '17 at 12:49

• In general: any spell-checking done in editable text boxes on a website is done by the browser; rarely have I seen a site whose text editor provides its own spell-check. – J. M. is a poor mathematician Nov 6 '17 at 13:45
