Suggest purging the cache on Moodle server. Also clear your browser cookies/cache.
Does it show? If not, turn on debugging then go to any mod/activity in the edit mode to see if any editor shows.
In addition to debugging on, might also check your web server error logs for clues.

Dear Ken,
thanks for your hint; after clearing cache, however, we got another problem with mathjax, see attached image.
Any help, please ?
Those are cloudflare content delivery network - javascript - errors.
Moodle, by default, isn't setup to run behind cloudflare, but doesn't mean that the makers of mathjax don't.
So, if you have ssh to your server, login and try using wget with one of those URL's:
Like this:
ktask$ wget https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js
--2018-01-16 14:19:24-- https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js

wget does acquire the file so don't do that inside your moodle code directory.
I see link that shows 'Learn More'! Uhhhhh ... does that link 'learn ya' any?
I also see it says there's an error ... but I don't program either.
Is your site set to use CloudFlare? Do you have access to CF 'control panel' for your site? IF so, turn off whatever is related to javascript caching and see if your problems go away?

Hi,
our smart admin got solution : the MathJax configuration was wrong and it had to be fixed to the form:
MathJax.Hub.Config({
config: ["Accessible.js", "Safe.js"],
errorSettings: { message: ["!"] },
skipStartupTypeset: true,
messageStyle: "none",
TeX: { extensions: ["AMSmath.js","AMSsymbols.js","mhchem.js","noErrors.js","noUndefined.js"] },
});
