Broken WP site after simple post automating

[Sayag678]

My website was OK.

but after posting using make my WordPress design lose it! in the header section indeed.

I made automation from WIX gathering data into Make using webhook,

then organizing the data variables and posting in WordPress (using Make plugin for API connection)

1. Why it can happen?
2. What should I do next time to avoid such situations?
3. There is a way to fix it without resote from server side?

Thanks in advance.

It’s possible that the submitted post contained bad code itself.

I would try logging into WordPress, and deleting that post.

Thank you.

Does it make sense when my post had few chars in title and in body for testing use only it can harm the website?
