Please elaborate on “An issue related to Rest API could also cause the JSON response error on your website”. I have no idea how to address this. What are the steps?

Could this have something to do with it? If so, how can I add these things and why don’t they get added automatically? Thank you.
]]>By the way have tried:
– manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.
– If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/
and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

Since then the block editor has stopped accepting custom HTML code.
Can you give an example of what kind of custom HTML code you’re talking about?
Classic editor is not giving this error. It is only the block editor. I am able to put a link in classic editor but if I go back to block editor after it will not save over the link and all data does not get saved. Because of this I can only use classic editor.
By ‘Classic Editor’ do you mean you installed the plugin for that? Or do you mean the classic blocks?
