Visual editor now displays a blank page, with only the HTML tab of the editor showing the content. Sometimes, I click on the html editor and then back to the visual editor and I can see the text content, but if when I repeat this sequence, neither the html or the visual editor show the content again.
Chrome console shows this error: https://postimg.org/image/y1fskdc7l/

Hi there,
The console error indicates that you have a plugin or possibly a WP theme function that’s loading in another version of the jQuery UI library instead of the bundled jQuery UI library. That’s a mistake, and the reason it’s a mistake is explained here:
https://developer.wordpress.org/themes/advanced-topics/javascript-best-practices/#use-included-libraries
You can find out which plugin or theme function is loading in the other version of jQuery UI by following these steps:
1) You can rule out a theme script by temporarily switching to the default WordPress theme, then test. The theme test drive plugin allows for testing another theme without actually changing your site’s theme.
2) You can rule this out a plugin conflict by temporarily deactivating any other installed WordPress plugins. Then you reactivate them one by one, while testing the error condition between each reactivation.

1) If I switch to a WP default theme, People visual editor shows text content only in two thirds of page width
2) If I deactivate all plugins, then my website goes totally blank and I have to restore a backup

Then you can deactivate plugins one by one. It seems you have at least one improperly coded plugin, and possibly some improperly coded theme functions that lack safety checks before calling functions from other plugins.

If I deactivate all plugins except EE and EE People add-on, the problem with People Visual Editor appears.

However, when I activate Advanced Custom Fields plugin, neither HTML nor Visual editors work anymore.

If I comment this line in ACF plugin:
`function input_admin_head()
{
//add_action( ‘admin_footer’, array( $this, ‘admin_footer’) );
}`
then visual editor appears blank, but works after clicking first in HTML editor.

You should probably contact Advanced Custom Fields support, and they can look into a solution for you that doesn’t involve removing scripts like that.

Solved this by editing wp-config.php and adding:
define(‘CONCATENATE_SCRIPTS’, false);
