Hi all, I am not a programmer but have managed over the years to use odoo independently.
In late 2022 I upgraded to version 14, it worked perfectly until a few days ago.
Now after selecting the database the login screen is not graphically correct. If I try to log in I get a blank screen.
By logging in in ?debug=assets mode everything seems to work but in some cases I get this error:

Error: Couldn't load css dependency: http://xxx.xxx.xxx.xx:8069/web/content/518-34f550b/web_editor.assets_summernote.css loadCSS

/urlDefs[url]

dispatch@http://xxx.xxx.xxx.xx:8069/web/static/lib/jquery/jquery.js:5183:27 

add/elemData.handle@http://xxx.xxx.xxx.xx:8069/web/static/lib/jquery/jquery.js:4991:28

Solved by reinstalling odoo 14
Thanks to those who took an interest.
