Refused to apply style from "css-file-path" because its MIME type ('') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Hii
I have installed  a Nop-Template theme in my NopCommerce 4.3 .It was working fine since a month.
now i changed some settings from  Admin Side in  a theme related to  menu .
and then i just clear and rebuild my project.
Now I'm getting the error "Refused to apply style from 'CSS  file path' because its MIME type ('') is not a supported stylesheet MIME type, and strict MIME checking is enabled."

I have reverted all the changes even from  admin side. Still no clue getting
it shows me the mime type error in  wwwroot/bundles/  files in  different different files.
I'm stuck . what going wrong with it .
At admin  side all the minification  checkboxes are also ticked for all  stores

Please check your web.config, is it default nopCommerce web.config or modified?
Specially check the marked portion.

Also, I would suggest you to stop CSS bundling and minification then try if the issue resolved or not, later on you may turn on CSS bundling and minification again.

Hii
I checked the marked portal  in  web.config. It is there. Also tried by stopping the css minification .
Same error is there.
Do I need to  uninstall the theme and reinstall again?

please try with restart of your project by deleting this folder

Experiencing the same issue, is there a resolution for this?

Thanks

Resolution:
Check the Cache directory location in App Settings

Can you please elaborate on this one? What directory should I put there?

I upgrade 4.30 to 4.50.1 from that day  I am also facing the same issue on all pages of  my website  http://www.smmotors.org

On first attempt page will not load properly, when we refresh that page again the page will be loaded properly.

Any Solution ???

sm4pk,

Check in ~\App_Data\appsettings.json the CacheDirectory value in WebOptimizer section.
It should be something like this:

"CacheDirectory": "~/wwwroot/bundles",

Perhaps it is set a local path

Thanks Carlos  Its work.
