'Visual Tab' Post Toolbar Not Working

Hello,

When creating a new post, or editing an old one – the ‘Visual’ tab does not show the toolbar editing icons for the post. (such as font size, color, underline, bold, all that).

Also, the entire post is gone (if I’m editing an old one) and I can’t click on the text field to type anything, same with trying to create a new post.

If I click on the ‘Text’ tab, I can type just fine and create my post, but I need to use the editing toolbar for specific changes, since I’m not sure how to add these using code. ??

I deactivated each plugin individually to see if any of these were causing the issue and there is one – the ‘Insert HTML Snippet’ plugin. Once I deactivated this everything started working normally again.

But this is a very important plugin for my site, and it was working perfectly fine the last time I used it, which was just this past Friday.

I have tried to contact the developers of the plugin to see if they could help with this but haven’t heard back yet, so figured I’d try here.

Any assistance is appreciated, thank you! ??
