Steps to repeat:

1. Create a survey, add a group
2. Add a new question and choose a type: "Select multiple choice image" >> without saving
3. Go to the list of sub-questions, click on the editor, then browse >> here's the problem
4. If I click Save question and then go to the subquestion and follow the instructions from point 3 >> the problem still occurs
5. Reload the page and follow the steps from point 3 >> now it works, you can add an image
6. Add some sub-questions (may be blank), click Save and reload the page. Now go to edit each of the sub questions you added, you can add an image.
7. Add a new subquestion to the list from point 6 (without saving and reloading), follow the instructions from point 3 - a message will appear that you cannot add a photo, go to edit the previous subquestion and try to add a photo > > this appears same error message although it worked before.

In my opinion, something is missing when adding a subquery, until the page reloads, it doesn't see it for the new subquestion, and blocks the image from being added. Worse, because triggering this lock disables this mechanism for all previous subqueries.

I installed LS v5.6.13 locally to verify the issue with this version (pure instance without our dedicated plugins).

Adds a new survey with a sample question created. I change the question type to "Select multiple choice image" (without saving), go to the list of sub questions, click edit and a new window opens "403, Invalid Group ID"

After saving the changes, I go to edit the subquestion, still the same error message.
I reload the page, go to edit the question and then edit the subquestion, ckeditor opens in a new window - there is no error.

Hello 2BITS_PL,
I checked this with the latest version and could not reproduce, so this is most likely fixed for good.
Therefore, I am closing this issue. If you still can reproduce the issue using the latest version, please feel free to re-open the issue.
Thank you!

Hello 2BITS_PL,

We have tried different ways and couldn't reproduce it.
I guess to know more about it the best would be to add some debug info on:

application/helpers/admin/htmleditor_helper.php
initKcfinder()

var_dump(Yii::app()->session['FileManagerContext']);
var_dump(Yii::app()->session['loginID']);
var_dump($_SESSION['KCFINDER']);

I have no way to verify it now, I need a few days.

demo.limesurvey.org (v6.2.5) - not resolved, step to repeat:

1. create new syrvey
2. go to the structure tab and add a new question
3. Open the question text edit
4. click on the image icon
5. click the "Browse Sever" button, then it returns the error "You don't have permissions to browse server."

Locally on v5.4.11 - I have the same thing.

I think demo is limited on purpose in terms of the resources browsing.
Sorry, that will not be enough for reproducing the issue.

Best chance is for you to do the debugging steps.

The topic must wait until I return from vacation, because I have no way of verifying it now. I will download the latest version 5.6.x and check.

Sorry for the notes in private mode - it's a habit from work ;)

I confirm that the bug does not occur in v5.6.37.

As per the comments, will be closing the ticket.
Please add any comments in case it should be reopened.
Thanks
