You have a few references to https://basel/ domain. You should be able to correct this while editing your slider with Revolution Slider plugin and removing thumbnails images for each slide.
Hello,
I removed all the images even from slider revolution..still the error GET https://basel/wp-content/ net::ERR_NAME_NOT_RESOLVED shows up in the console.
What more can i do to get it resolved?
Are there more references to the dummy content of basel theme?
