Cannot Edit Nimble Built content

Hello,
Thanks for opening this topic. I don’t know how to reproduce this problem on a test site, everything works fine on my end.
You’ll need to follow the troubleshooting steps hereafter to help isolate the possible cause of the issue.

1. Use the latest software versions : make sure WordPress, your theme and plugins are all updated to their latest versions.
2. In your WordPress admin, go to settings > general and verify that your WordPress Address (URL) and Site Address (URL) are identical. The website will not run properly if the urls are different.
3. Cache plugin : if you use a server cache or cache plugin, clear it’s cache content and disable caching via it’s settings.
4. Browser :

• clear your browser’s cache / history,
• try to switch to another browser,
• make sure you do not use any add-ons or extensions in your browser that may conflict with your website.

• Check for plugin conflict : Install the WP official Health check plugin. Activate the troubleshooting mode. Then deactivate all of your plugins. If it fixes the issue, re-activate your plugins one by one, until you identify the plugin in conflict.
• Child theme : activate the parent theme if you use a child theme
• Theme problem : try to activate a WordPress default theme ( Twenty … )
• Javascript : make sure you did not insert custom javascript code ( like analytics, subscription popup… ), for example in a widget, that could break your site.

To log possible code errors on your website, enable WP_DEBUG mode and log the output of the debug.log to a file that you can share on https://pastebin.com/ or https://gist.github.com ( to get a debug log file you need to set define( 'WP_DEBUG', true ); and define( 'WP_DEBUG_LOG', true ); in your wp_config.php file.
