JATOS study resulting in blank white browser page
For my thesis I decided to create an online study using OSWeb and JATOS.
The implementation worked out pretty well and my professor organized a Linux Redhat server from our university.
However, we're experiencing some problems now. Whenever we try to run the study (directly on our own JATOS server or via a worker link) the experiment doesn't start but only shows a blank white browser page and nothing happens.
Here is what we did so far:
1.) I created the study using OpenSesame (v3.2.8); the study displays 210 images to participants, images are in the file pool
2.) I exported the study directly as a .zip file using the OSWeb exportation tool in OpenSesame
3.) I already imported the study on the JATOS tryout server and it works perfectly fine there
4.) We also tried out some other example studies on our own server which seem to work fine as well
5.) We imported the study on our own JATOS server (which is being administered by my professor) and here the described problem occurs; somehow we just don't get the study to start ...
Any idea what we could have done wrong here? Maybe an error with the study_assets_root folder or loading the images?
We found that JATOS properly creates the assets folder of the OSWeb experiment with a long cryptic name such as "a89ed34bdd..." and it also contains some subfolders like css, img, js, an index.html and the OpenSesame experiment file. Img only contains opensesame.png and warning.png.
Do we maybe have to add the images manually somewhere?
If you need any more details, please tell me. Maybe you could help us out :)
Ultimately, we plan to write the study up as a paper and we would love to give both OSWeb and JATOS some credit for the amazing work.
Thanks very much in advance,
