I have a problem with themes from previous versions. One of the problems is the following:

You can not see the writing box when creating a theme.

Also I have found something similar in other versions, the box looks but does not let write in it.

How could this be solved?

Thanks

what is your forum url & which theme you are using ?

you can try changing the editor style at the theme properties

forum admin panel >> Templates & Style >> themes >> scroll down for edit theme properties
--> editor style
