I'm trying to use the custom code block and the editor is coming up blank. The default "Hello World!" text is visible on the page, but nothing in the editing block (see image). Things I have tried that did not fix it:
commented out all of my custom code and CSS
turned off my browser extensions
logged into squarespace on a different browser
logged into a different squarespace account
Has anyone else encountered this and did you find a fix? This is the first time I've ever had a problem like this and I'm stumped. Thanks in advance for your input.
