Description of the problem:  
I have an experiment that has a lot of custom code added to it. When I tried to pilot run the experiment, Pavlovia produced the error “403 Forbidden nginx.” I tried pilot running a dummy study with no code components but the same error was generated. I also cannot view my experiment’s code. I think part of the problem may be due to the experiment in PsychoPy not syncing with Pavlovia. Does anyone have a solution to this problem? Any help is greatly appreciated!
