HTML being stripped from shortcode blocks in blog posts

[kmwade]

Hi team

I have a MailChimp newsletter signup form in the sidebar of my blog. Occasionally I add the same signup form to the body of my blog posts. Previously when I have done this, the one from the sidebar has been removed and just the one in the blog post is displayed.

I tried to do this yesterday and discovered that wherever I have done this, now neither signup form shows. I asked my tech guy to take a look and he found that whenever the shortcode for the newsletter signup form is included in a blog post, the HTML is being stripped from the code meaning it’s not displayed. He suggested I try adding the form to a blank page and embedding it in my blog post to fix the issue. I did this using Elementor and it didn’t work.

My tech guy is fairly sure this is a bug as he doesn’t think any of the HTML should be being messed with. And he said he’s fairly sure it’s a WordPress bug not a plugin or theme bug.

I am unsure how long this issue has being going on for. Has anyone else reported a similar bug?

I’m using the latest stable version of WP.

Hi @kmwade. Are you still running into this issue? Does it happen if you disable all plugins except Mailchimp and activate a default theme e.g. Twenty Twenty? Could you please share the shortcode that are you trying to insert?

Thank you for reporting this, my hope is that because you have not replied this has resolved. That said, it might be the case you are still experiencing this and in order to progress things we do need a little more information. Until we get that, I am going to move this to closed, but we can always review that and anything can be reopened.
