Hi,
The two problems are related: if PennController succeeds in fetching the zip archive, it should rapidly preload all the resources it contains in the cache and thus no longer need to look for them at the beginning of each trial.
It’s possible that you don’t have the privileges to use .htaccess to configure CORS settings on your server, or maybe it’s doesn’t run apache. Would you mind sharing the link to your experiment with me (you can email it to me if you don’t want to post it here)? Just make sure to re-enable the Debug feature in case you turned it off before
