Hi all,

Whenever I want to save Javascript in a question, the following error pops up when I want to save the question:

Internal error from saveFormWithAjax: no data.responseJSON found

I nearly always get this error when I try to paste in Javascript in my surveys. I have been able at times to get around it, by removing a lot of what I think were the offending pieces of code, but it makes me feel something is wrong with my installation. I have had this problem in quite a few versions of LimeSurvey which makes me believe it is a setting in LS or on my server rather than something else.

To test whether there is an issue with my JS, or it's something else, I have just downloaded the following survey:

www.limesurvey.org/manual/images/9/97/Pa...anomized_Answers.lss

I uploaded this survey, and tried to edit one of the questions, and it gives me the error as well.

I have attached a screenshot of my security settings in case it may be relevant. I have Googled the error, but it doesn't give me anything that seems helpful.

Your LimeSurvey version: Version 5.3.2+220302
Own server or LimeSurvey hosting: Own server
Survey theme/template: Standard template
==================
(Write here your question/remark)

Can you explain what you edit and save to trigger the error?
I have used the survey you linked and imported in the demo installation of LimeSurvey.
I wasn't able to reproduce the issue. LimeSurvey 5.3.6 (you used 5.3.3).

I recommend to check on your own in the demo installation.
You might check the editor settings. Perhaps you use an editor mode which destroy the JS. Or your LimeSurvey version contains a bug.

My steps are:

1. Create a new survey by uploading the file mentioned.
2. Go into questions and choose edit Q1
3. Don't make any changes
4. Press Save

I understand that this should work OK in a demo installation, so there must be something wrong with my installation. How do I find out what is wrong?

My WYSIWYG editor does look different from the editor in the demo installation (see attachment). Is that what could cause the issue? 

That's only the hamburger button that expands or collapses the menu.

Thanks Joffm, this is what I see in the demo. 



I am guessing though as you have a similar menu, that this editor shouldn't be the cause of the problem.

Just to be extra sure, I changed my Default HTML Editor Mode to "HTML Source" however the error still occurs.

Well, it is not reproducable.

You'd create a new installation from scratch into a different directory, or just in XAMPP.
That's done in a few minutes.

Just created a new installation, same server, same version of LimeSurvey.
Uploaded the sample survey, and got the same issue.

My LimeSurvey installation is installed through Installatron, on PHP Version 7.3.33 and MySQL Version 10.3.34-MariaDB.

I just tried the same in a fresh installation of version 3.1.1 and the problem disappears in that version. 

I recommended to use a newer version. You had 5.3.2.
The demo is 5.36. The last community version ready for download is 5.3.7.

Do you maintain a complete webserver or do you use a hosting offer?
Sometimes there is a protection layer on webhosting or PHP settings are preventing correct editing and saving of questions in LimeSurvey.

Hi jelo,
I have tried a different version just to see whether the issue would disappear. I am with a webhost, using Cpanel. 
Using Installatron I have tried the following versions:

5.3.2 - Error appears
4.5.0 - Error appears
4.3.0 - Error does not appear, but I am getting different errors, relating to empty error codes (there are no empty codes), and a 403 Forbidden error when the question did save successfully
4.2.0 - Error does not appear, but I am getting different errors, relating to empty error codes (there are no empty codes), and a 403 Forbidden error when the question did save successfully
4.1.14 - Error does not appear, but I am getting different errors, relating to empty error codes (there are no empty codes), and a 403 Forbidden error when the question did save successfully
3.28.1 - Error does not appear
3.1.1 - Error does not appear

Are you saying I should upgrade from 5.3.2? Noting that Installatron does not allow me to upgrade beyond my current version 5.3.2.

Using Installatron I have tried the following versions:

Okay, then we probably are out.
These installers mostly have a customized versions that may cause problems.
