Pavlovia will not initialize the experiment

URL of experiment:

Description of the problem: After clicking the link, the screen freezes on “initialising the experiment”. Web developer shows me a “Loading module from “” was blocked because of a disallowed MIME type (“text/html”).” error. This runs from the “run” key in the Pavlovia but when I try to use the url for the experiment, it fails. I would appreciate any help.
