Hi there,

I am using Lando v3.0.0-beta.47 and Docker Version 18.03.1-ce-win65 (17513) on Windows 10.

The whole download process to my local machine works fine (no errors), but when I visit my site in the browser, the site gets shown without CSS Files. The Console says Refused to apply style from '' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

After disabling the "CSS Aggregation" in "Configuration -> Performance" it will show the site with stylesheets enabled, but I have a sitewide error saying

The File could not be created.

I have no clue how to get my site running correct again locally.

I would appreciate any help...

Thank you!

@ekoessel , you may want to look into It will help you pinpoint whatever permission issues you may have on your appserver container. It worked for me.

I'm seeing this error on a site in Lando. This error doesn't appear on the live version of the site on Pantheon.

The agregated css is in sites/default/files/css directory.

The problem is the permissions in the files directory, sites/default/files should have 755 and have 750

You can change the permissions with:

chmod 755 sites/default/files

This should be resolved as a consequence of #1325
