Hi Jeremy,
thanks for your fast reply!
Yesterday it showed me the 404 error in the console. The pictures preloaded,but they were not displayed. When I click on the experiment today, it was working fine at first. After running the experiment a few times to check if all pictures are displayed correctly, the zip file got downloaded (reported in the debugger), but the pictures are not shown at all (also the pictures I load locally from PCIbex is not shown)
This was shown in the console:
server.py?include=js:880 Uncaught (in promise) TypeError: Cannot set property ‘style’ of null
at l.uponCreation (server.py?include=js:880)
at l.n.uponCreation (server.py?include=js:880)
at server.py?include=js:880
at new Promise (<anonymous>)
at Array.<anonymous> (server.py?include=js:880)
at server.py?include=js:873
Most times I run the experiment, the pictures are shown, but sometimes nothing at all is displayed after the dashed sentence. I am afraid that this will happen when running the experiment with participants. Do you have an idea what is going on?
