FYI I installed the Classic Editor plugin and now everything works fine. So the block editor was causing the problems.

I’ve updated WordPress to version 5.3.2-ca

Now the error message says “Update failed. Error message: the response is not a valid JSON response”

I have no “site health” tool. I’m using the default set up of WordPress. Where can I check if REST API is enabled?

Thanks

Block editor

The online editor, both visual and code views.

Hi,

I had the same problem:

Fatal error: Call to undefined function qtranxf_save_languages() in /mnt/webr/b1/04/54599704/htdocs/wordpress/wp-content/plugins/qtranslate-x/admin/qtx_activation_hook.php on line 50

The language selected in /wp-admin/options-general.php page was Catalan. I changed it to English (US) and then the activation went correctly.

Thanks for the information above!
