Contact form “send” button suddenly ineffective

What other plugins and theme do you use on the site?

Theme :
The Place Child Version : 0.1 (based on The Place Version : 1.9.3)

Plugins :
Classic Editor Version 1.6.3
Contact Form 7 Version 5.7.5.1
Display PHP Version Version 1.7
Google XML Sitemaps Version 4.1.8
qTranslate-X Version 3.4.6.8
Slimstat Analytics Version 5.0.3
Sucuri Security Version 1.8.37
UpdraftPlus Version 1.23.3

I just tried disabling all plugins (except Contact Form 7, of course) very temporarily to see if it changed anything. It apparently didn’t.

The above error log was from Firefox javascript console.
Similar error reported under Chrome (appears when clicking the “submit” button on the contact form) :

Try switching to the default theme, deactivating all plugins excluding Contact Form 7, Classic Editor, Google XML Sitemaps and Sucuri Security, and clearing all cache data.

Why you are advised to deactivate plugins and switch to the default theme.

OK, I made multiple tests, and confirm the conflict occurs only when the theme “The Place Child” is activated (my plugins don’t make a difference).

Darn. What now?

Please do let me know if I can help problem determination in any way.

From other recent problem reports here, it appears the latest update to Contact Form has made it fragile to what may or may not be “oddities” or “improper/unexpected behaviors” in various themes or plugins (in my case the “The Place Child” theme).

If there are common issues that can be identified, you may be able to render CF more solid and avoid the pitfalls. Or you can decide it’s not your problem.

If this incompatibility will not be addressed semi-promptly, as I cannot move to another theme, I would have to select a CF plugin substitute (curently have just removed the contact form altogether, as a stopgap temporary measure).

Please do communicate on your intentions.

OK, sorry you couldn’t/wouldn’t address the issue.
I am moving to another form plugin.

Thanks anyway for the free use of this free plugin for several years, it was fine while it worked !
