Every time I try to run my experiment it comes up with this.
and says not found or error. Do you know why this might be?
Your file path starts with…/ which means you are trying to load a resource higher up the directory tree than your experiment. This was fine when JavaScript files were copied to an html folder but nowadays they are in the same folder as the psyexp file. All resources should be in that folder or sub folders.
OK so how do I resolve this?
Do you currently have an html folder? If so, then delete it, remove html from Experiment Settings / Online and sync again.
How are you attaching your resources? If it’s via Experiment Settings / Online then I’d try again after you’ve removed the html folder.
