Ok, then this sounds like something @Daniel might be able to answer, as it's related to OSWeb, not JATOS. From the little I know, the issue is probably that you are relying on some features that work on OpenSesame will not work on OSWeb. Best
-
Hi, this is weird, let's check first: Are you running two different versions of JATOS on your laptop and on the server? If which is the version t works for and which doesn't? Best
-
Hi Afkeve, This was an issue that had to do with the combination of how OSWeb and JATOS were set up. See one of the other threads with the same problem. (e.g. https://forum.cogsci.nl/index.php?p=/discussion/5934/missing-trials-in-data-file) It's be…
-
Hi, Actually there's a misunderstanding. The endPage.html is means to be a static, custom webpage that you might want to show to your participants. JATOS already automatically displays an MTurk confirmation code whenever you use an MTurk worker typ…
-
Hi Marita, That's odd. The error message is clearly wrong. Just to be sure, can you please try: In your local JATOS, clone the study (on the study bar, go to more -> clone) Export the clone Try to import it on your server. The reason I'm sugges…

Hi Marta, I will try to answer below. But all these things are harder to describe than to actually try. I recommend that you just try it out and ask again any other problems you have in implementing your solution. Does the link contain any inform…

Hi Victor, It's hard to help without more details. So here come a few questions: -What changed between the time it worked and when it stopped working? -Why changed between the 404 and 403 errors? -What happens if you re-export the study from lab.js…

Hi Marta, I am designing an experiment that will be run on JATOS and I am not sure what kind of worker type to choose. Since my experiment will be long, I want to give the participants the possibility of not doing it all at once. I have thought abo…
-
Without more information, it's hard to know what the problem is. If you open the Developer tools in the browser, do you see any error messages in the console? What did you change that made it not work anymore? Does it work with some worker types an…

Hi Victor, Happy to hear you're finding JATOS useful! Links don't expire over time. As long as a participant clicks on the link once and doesn't reload, it will always work. Personal-single or General-single links can be used only once, which is …
-
Hi Nikita, You have three options: As Vatsal said, you could install JATOS on your own Digital Ocean account You could expose your local installation to the www. We explain how to do that in our docs. This option works, but is not the most stable…
-
And @Daniel and @kri , As Kristian said, I agree with you :) We introduced the Allow-preview thinking of a study with multiple components, and assuming that the first would always contain some version of information + consent form. But I'm aware t…
-
Hi @Simona, The allow reload box is a property of each component. On each component's bar, click on Properties and you'll find the checkbox below the Title.
-
Hi Simona, In that case, go to the Study Bar -> Properties and check the box that says 'Linear Study Flow'. That will only allow people going forwards. If they try to go backwards, they should get a pop-up warning them, but it's very important …
-
Hi Simona, The comment should be visible if you go to Worker and Batch manager -> All Workers Let me know if you can't find it. Best Elisa

The short answer is yes. Even if you update the study scripts, the link to it will remain the same.
-
Actually, I just remembered that we also have an example study doing this (so it's a lot better than my messy, idiosyncratic example). Check the example "Randomize Tasks Between Workers" in our example studies page: http://www.jatos.org/Ex…
-
Hi Penguin, You are right: it's a bit difficult to ensure that you have exactly the same amount of participants per condition, because it's possible that as one participant is completing the task, another one is starting it. There's no real way aro…
-
Hi Marta, This is really a very basic example (it's not an actual experiment, it's just intended to show the new "file upload" feature, but we do have an minimal script to collect and upload audio files: https://github.com/JATOS/JATOS_exa…
-
Hi, Kristian will correct me if I'm wrong but there's no change to the abort behaviour. jatos.abortStudy will delete any data stored up until that point. Note that if a participant closes the tab, the data will remain by default. You would have to…
-
Hi Vatsal, Usually that error message appears if all components in a study are marked as inactive. (In the case of OSWeb studies, there's only one component). What happens when you log in to JATOS and go to your study? There is a checkbox on the lef…
-
Hi Orin, First, don't panic. Even if you can't export your data, they are in the database and there will be a way to access them. Still, you're right that it's a very good idea not to update JATOS until you've safely exported everything. The issue…
-
Hi, Can you give us a little bit more details? Where exactly did you add the command jatos.startNextComponent() ? I assume you saw this other answer. Did you manage to modify a line in the HTML script itself and replace jatos.endStudy() with jat…
-
Just a quick thought, for both @maj_zmaj and @christinaverena : are you sure that you first unzipped the entire JATOS folder? If I remember correctly, windows lets you look into and open files from a zipped directory without really unzipping it firs…
-
Hi, We need more details to troubleshoot your problem (because we just tried JATOS v.3.5.3 on a Windows 10 pro and it worked): which JATOS and OS version are you using? Elisa
-
Hm, let's see. Point 3 is dependent on Point 2. Were you able to export the properties of the OSWeb component, and save the properties file as .jac file on your Desktop? You have to click More>Export on the component bar. The .jac file is what…
-
This does not exactly have to do with JATOS, but with OSWeb. @Daniel might be able to help?
-
Hi Andrew, If you could tell us what error messages, if any, you see in the console, we'll figure out where the problem is. But also, you can add a counterbalancing script in JATOS if you're willing to write a bit of JavaScript. We have some examp…

This is not a JATOS question but rather an OSWeb one, @sebastiaan might be able to help
