   block editor was causing the problems.

 * 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

 * 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!
