This is a very strange issue you experience. When I visit your website, it loads immediately (a second or so, both on Firefox and Chrome on Windows) for me with no error in web browser console. You can actually see for yourself here: https://gtmetrix.com/reports/bbqin.uk/uChpg7lt
Do you still experience the issue on your side? If so, try to disable your browser extensions and flush the browser cache. Or try a different browser.
