I have a Magento 2 multi-website with each website has their own store view, after I upgrade it from 2.5 to 2.3.3, the main website is looking fine, but the others are broken and when I inspect, got an error like this:
(index):1 Refused to apply style from 'pub/static/_cache/merged/0cb08dac7714064caf47f5c9bb91fcb6.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
* I already deleted the pub/static/frontend and make sure the pub/static/.htaccess is there, and run:*
bin/magento cache:clean bin/magento setup:static-content:deploy -f
but still got the same error
