Conditional branch function stopped working

Thank you for your help.

There was a problem that Conditional Fields did not work in WordPress.

It did not work even if I verified it with the code described in the tutorial created by Jules.

I’ve tried all the check items in Troubleshooting, but nothing worked.

I tried changing the theme and it worked fine.

The theme that causes the problem is “Affinger6”.
“JIN” and “Twenty Twenty-One” are the themes that have been confirmed to work properly.

Even “Affinger6” was working normally until June 2022, and it was usable comfortably, but in September, a problem occurred.

I contacted the developer of the theme, but they refused to answer, “I can’t answer questions other than those developed by our company.” So, in the end, I emailed Mr. Jules.

Could you please let me know if there is a function code that solves the cause of this problem?

You may think “I should use a different theme”, but Affinger6 is a paid theme that is not cheap and is easy to use, so if possible, I would like to use this theme as it was a few months ago. I would also like to be able to use

I would be very happy if there is any solution.

thank you.
