Multiple JS warnings on admin form prevents saving

Unable to replicate.
Saves fine for me without any error.

@euanfergusson Do you still face an issue?

@euanfergusson, which browser, browser version and os are you using? Did you upgrade from an earlier version of the module or was this a fresh install?

I'm also having this issue. I cannot save the module configuration.

Latest Firefox gives a distinct JS warning:

Chrome also gave me JS errors (not warnings) the first time I installed the module and went to the module configuration page, though I can no longer replicate them after messing with the configuration page to try to get it to work.
Chrome errors mentioned something about 5 non-focusable text areas being invalid.

What I did in Chrome was:

• changed the text formats to a custom one that allows PHP
• filled required fields and ticked all of the user roles
• saved

and then the page refreshed, I was given a green success message at the top of the page, but none of my changes saved and I was back at square 1, except the errors were gone.

In Firefox it's still the same. In Chrome it gives me no errors but saving doesn't work even though it's giving me a green success message. I tried reinstalling the module several times, clearing cache etc, but nothing has worked so far.

Same error here, after an upgrade to 10.1.4 my old cookieconsent module wasn't compatible anymore. I installed this one, but have similar issues as above

I wasn't able to replicate this, tested this on Firefox and Chrome (PHP 8.1, Ubuntu 22.04).

I fixed it in my installation by creating a fresh install (1.24) on https://simplytest.me/. The I exported the default config and imported it on my site.

After that, I was able to use the config on the site as normal.

@euanfergusson, @Rares Petru Samartean or @parijke, I've tried saving the admin settings form in Chrome 118 and Firefox 118, for both Drupal 9 and 10, and can't really reproduce the issue. Do you have any additional details?

I'm going to close this one as several people are not able to reproduce. If you still have the problem, would you be able to set up a test site where I can log on and inspect it further?
