I hoped for some connection error. But that is just the error that gets logged if the authentication failed, e.g. username or password were incorrect. In your original message you wrote 'disabled SELinux' - can you elaborate on this? I'm not familia…

You could setup a static welcome page and then configure the URL base path to 'hide' JATOS in a path. E.g. you could have a static welcome page under https://jatos.example.org/ and then JATOS under https://jatos.example.org/whatever/. Would this hel…

Hi! Although they say it's possible I've never seen a server actually doing it. It's very unusual. You have to get a certificate on your IP though. Then JATOS doesn't care for it and as far as I know Nginx/Apache too. I would not recommend it. Can't…

Sorry, there is only one logging mode. What does your application.log say?
-
Since version 3.5.9 you can customize the home page: https://www.jatos.org/Customize-JATOS-Home-Page.html Unfortunately the login page itself is still not possible to customize. But you can have some kind of static front page (like they do with mind…

Either is fine

Hi Bo, What you describe is possible. Like you suggested I'd start with the Prisoners Dilemma example and change it to your needs. The rough study flow could look like: You need a waiting room component for 8 people When all 8 participants joined as…
-
Hi Chi, The easiest way to fix your experiment is to encompass your whole experiment, everything in startExp function, in jatos.onLoad and have the initialization of Part_ID in the beginning: function startExp() { jatos.onLoad(function () { va…
-
If you share your experiment with me I can have a look at your code. You can send me your experiments jzip if possible. Best, Kristian
-
It is a JavaScript issue. The scope of your Part_ID is limited to startExp function. You have to declare it as global variable first and then you can use it outside of startExp: var Part_ID; // global variable declaration startExp(); var condition…
-
Hi Shay, Yes, it means your study is too large. What is the file size of your jzip file (the one you want to import to JATOS)? Best, Kristian
-
Hi Bo! If I understand you correctly you want to use jatos.groupMemberId to assign a participant to a role based on it being odd or even. That's not a good idea - it will only work on your local JATOS but not on a JATOS server where there are potent…
-
Hi Chi! I took the liberty and formated your code to make it more readable. Your startExp function looks fine. When do you call assign function? Is it maybe before startExp? Then Part_ID wouldn't be initialized yet. Best Kristian
-
Hi! You have to wait for jatos.js to be initialized. Only then you have access to these IDs: jatos.onLoad(function() { var PartID = jatos.workerId; }); Best, Kristian
-
Hi Bo, there aren't any other group study examples as the ones in https://www.jatos.org/Example-Studies.html. Writing and conducting group studies can be a bit tricky due to participants acting in parallel (but nothing impossible). Can you describe …
-
Hi Chi! Your experiment looks doable on Mindprobe. If the result data stays at around 600kB per study run it shouldn't be a problem. But it's important not to have to many overlapping participants. It's probably best to have a test run with just a f…
-
Ah, yes you are on some cloud server then? Did not think about this. Nice you solved it. You can ignore warning from 'com.google.inject'. Do you have others?
-
Hi Bo, Your issue is likely different from David's. It looks like you want to start JATOS on port 80 on Linux, correct? Since port 80 belongs to the privileged ports you need to start JATOS with root user (or some similar user). If you want to run J…

Hi Margaret, Like I said Mindprobe is not overloaded and I guess the reason is more on the browser side. Do you have any errors in the browser or do you have a way for me to reproduce the problem on my computer? Can you give me a link to your study?…
-
I had a look at your study. It's more complicated than I thought. My idea with jatos.removeOverlay does not work. But fortunately there is way to completely turn off those overlays from the start. Just add jatos.waitSendDataOverlayConfig = { show: f…
-
Hi Margaret, Mindprobe is working fine and is by far not overloaded. May I ask which worker type you are using to create your link(s)? The error message your participants reported (“It's not allowed to reload this component. Study is finished.”) ind…
-
Hm, it doesn't fix the problem ... do you have an error message or is there no error? Or can I somehow have a look at your study? If it's possible you could send me your study (the exported jzip) or make me a member of your study on jatos.mindprobe.…
-
Hi, Can you tell us a bit more how you installed JATOS? And what does JATOS' log say? Any errors there? You can find the log in your JATOS folder in logs/application.log. Best, Kristian
-
Yes, it's a bug in the current jatos.js (version 3.6.1). In some cases with jatos.endStudyAjax or jatos.abortStudyAjax this can happen. The next release (should be 3.7.1) will include the fix. Until then you can use jatos.removeOverlay to remove the…

Hi! First, please no cross-posting between the JATOS and OSWeb forums. It keeps the forum clean and our work to a minimum. And if we notice that the post belongs in a different forum we forward it. I think you should use 'uid' instead of 'UID' - th…

Cross-post. See answer in: https://forum.cogsci.nl/discussion/7358/id-particpant-for-osweb-experiment

Now I could reproduce the problem. Before I had Chrome's Dev Tools turned on and they turned off any caching 🙄. I checked the JATOS' code: The cache-control header is hard coded to max-age=3600 (1 hour) for the branding response (customized home pag…
-
Hi Fabrice, It seems there is an issue with your customized page's cache instructions. I'm not sure if this is a general problem or just with your page. I just checked on jatos.mindprobe.org and there it works with me (at least with Chrome). Where d…
-
Hi! Usually source map are not necessary to run JavaScript, they are a readable version of the program for debugging and developing. So if your study doesn't work anymore there is probably another cause. Are there other error messages? Any hints for…
-
Hi Marion, Great that you like JATOS. It's always nice to here that people find it useful. Did you try version 3.6.1 already? There are some nice things for admins. And about the study asset root: Yes, you are correct, all studies share the same stu…
