We are trying to create a template after making some fields. We added just one photo to the template as an initial test, but we got this error message "Updating failed. Error message: The response is not a valid JSON response." What have we done incorrectly?
It seems something is interfering with the AJAX calls.
Can you ensure this as well happens with only Toolset and Theme Twenty Twenty (eventually on a testing site) and if so, could you maybe zip that site up and send me a copy of?
It's described here how to do that https://toolset.com/faq/provide-supporters-copy-site/
I can then have a deeper look. If you instead find a Plugin or other Theme to be conflicting, please let me know as well, so we could analyse that too.
It would be useful knowing if here are any errors in your browser's console, or any errors are logged when you enable WP Debug, as well: https://codex.wordpress.org/WP_DEBUG
Thanks!
My issue is resolved now. Thank you!
I used the reference site but I played around with the field group and deleted existing custom fields leading to JSON error.
Thanks for the help.
