TOC shortcode not rendering

Hi, Sorry for the inconvenience caused you. This is because WordPress has released a new version 6.2.1 with some security fixes but that has caused many websites to stop working on shortcode.

Here is the reference article to know more on this: https://www.searchenginejournal.com/wordpress-update-6-2-1-causes-some-websites-to-break/487358/

Thank you very much for your reply. I read the article you shared.

Security first so I’ll stop using shortcodes.

Hello, WP 6.2.2 solved the issue. However, the future is no shortcodes.

Do you have any plans to go full in Gutenberg? If you use blocks instead of shortcodes, your plugin will be future-proof.

Thank you for your consideration.
