"Miracles do happen", one would think, but this was not a miracle. Someone out here must have worked hard to fix this. Thank you very much. :)- ~~~~

Thank you for your time Mbch331. I tried the word [https://en.wikipedia.org/w/index.php?title=Coin&type=revision&diff=947626818&oldid=947610147 coin]. Now, after clicking the Preview/Save button at bottom, I get https://en.wikipedia.org/w/index.php?title=Coin&action=submit and nothing happens, the page is blank, apart from a tekst appearing on the bottom:
: ''Deze tekst is gewijzigd in Internet Explorer om scripting om meerdere websites te helpen voorkomen''. I guess I am too stupied for that kind of stuff.
