Export HTML does not create files

URL of experiment:

Description of the problem:

I have an experiment programmed in v3.2.4. File - Export HTML creates an HTML folder inside the experiment folder containing the .psyexp file. The HTML folder has a a Resources subfolder, but does not contain any HTML or JSON files. When I sync with Pavlovia, and then try to run the study online, either via Builder or by selecting Pilot on Pavlovia, I get sent to a 403 Forbidden page. I guess this error is due to the HTML folder not being populated.

So the question is why is Export HTML not working?

I would update to 2020.1.3 and try again.
