I’ve just upgraded to EE 3.5.17 but now the control panel has no CSS, the developer console shows
Did not parse stylesheet at ‘https://www.website.com/themes/ee/cp/css/common.min.css?v=1599559236’ because non CSS MIME types are not allowed in strict mode. jquery.js:1
How can I fix it?
I resolved the problem by making sure the themes folder was in the right place and with correct permissions
