Update to latest version – error

Hi there,

after updating to the latest version we get this error on the frontend, which prevents the site to load MAPS/SEARCH RESULTS.

Refused to apply style from ‘https://<ourdomain>/wp-content/plugins/geo-my-wp/plugins/posts-locator/templates/search-results/fitnesshire/css/style.css?ver=5.6.1&#8217; because its MIME type (‘text/html’) is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Any idea ?
