1. Install a clean nopcommerce 2. install Two lang first ltr second rtl 3. Uncheck setting in Bundling & minimization ->Css bundling and minification 4. In front end change to the rtl lang
Couldn't reproduce. Perhaps this is due to non-Latin characters in the path to the app files. Try to change the Cache directory setting to ~/wwwroot/bundles value. Lets me know if it helps you, please.
