Hey guys, I fixed the problem by going to Internet Explorer, thanks for everyone's contribution!

try clicking on the little x in the top right corner of the editor box -that may expand it....

Alright guys, I'll try that out later and let you guys know if it works

have you tried clicking on the text tab at the top
and click on the fourth menu item from the right and this will give you a second line of menu icons
did you create the article in the classic editor or the block editor
i hope you get it sorted
