 * Hello,
 * I have just upgraded to WordPress 5.6 and upgraded the plugin to match.
 * The editing windows is blank and I can’t use the menu of editor just above the
   text bloc.
 * When I display text I see text and in Visual display I see nothing or text without
   style.
    It doesn’t work on all of my product pages, categories, etc.
 * I read your support [https://wordpress.org/support/topic/common-classic-editor-errors-and-how-to-fix-them/](https://wordpress.org/support/topic/common-classic-editor-errors-and-how-to-fix-them/)
   but nothing works.
 *  I emptied my cache and installed the plug in [https://wordpress.org/plugins/enable-jquery-migrate-helper](https://wordpress.org/plugins/enable-jquery-migrate-helper)
 * I had no problems identifying on the plug in and no warnings about the outdated
   scripts
 * Thanks in advance for your help !

 * Hello,
 * Just to add an information, in all my pages in admin, all texts are without customization.
   
   And as you can see in the picture, the font and others things are by default.

 * I can’t make any changes to my site.
 * Thanks in advance for your help !

 * Hi [@tibofnt](https://wordpress.org/support/users/tibofnt/),
 * Unfortunately cannot pinpoint where exactly the error comes from. Looks like 
   you’re using a commercial plugin(s) for Woo, perhaps this one: [https://woocommerce.com/products/products-by-attributes-variations-for-woocommerce/](https://woocommerce.com/products/products-by-attributes-variations-for-woocommerce/).
 * The problem is that the above plugin loads an old version of jQuery UI, v1.11.4
   as seen here: [https://lerepaireduchef.fr/plug-extensions/show-products-by-attributes-variations/assets/js/jquery-ui.js?ver=1.0](https://lerepaireduchef.fr/plug-extensions/show-products-by-attributes-variations/assets/js/jquery-ui.js?ver=1.0)(
   which looks like all of the UI code in one file).
 * However there is another part of jQuery UI loaded from WordPress, `jQuery UI 
   Sortable 1.12.1` here: [https://lerepaireduchef.fr/chemin-inclu-path/js/jquery/ui/sortable.min.js?ver=1.12.1](https://lerepaireduchef.fr/chemin-inclu-path/js/jquery/ui/sortable.min.js?ver=1.12.1).
 * This shouldn’t happen (loading different versions and different parts of the 
   same script), and is what causes the errors.
 * Perhaps try updating all of your plugins to the latest versions and “clear cache”
   for any/all WP caching plugins you are using. (I’m not sure where the `[site.
   url]/plug-extensions/...` path comes from, looks like caching. Or perhaps it 
   may be a custom plugins directory.)

 * Hi Andrew,
 * All my plug in are update and I have the same bug.
 * I will contact product by attributes.
 * Thanks for your help.
