Hello,

I am running a token-based survey where LimeSurvey generated the tokens and I send out invitations/reminders via email. There are many responses that show "complete" in the response table but then that same response shows "incomplete" in the token table. Because of that, I have many clients that are upset because they've been getting reminder emails for surveys they have already completed. There are also cases where there are "incompletes" in the response table but then showing "complete" in the token table. This is an even bigger problem because now those people aren't getting reminder emails.

Has anyone had this problem before? Does anyone have a solution? Should I report as a bug?

Sorry. Forgot the essential details:

Version 2.06+
Build 160123

Also, it looks like people are accessing the survey more than once with the same token, even though I have "Allow multiple responses or update responses with one token?" set to NO and I also have persistence turned ON

Hi,

Seems strange ... Can you reproduce the 2 issue with a very little survey ?
Did you have some extra external plugin ?

Hi Denis,

I am trying to reproduce the issue now. There are no plugins. I will add 2 details:

1. I imported this survey structure from a previous version (Version 2.00+ Build 131107).
2. Respondents are reporting that when they go to click "Submit" at the end of the survey, an error message says that it did not go through (I haven't been able to get anyone to send a screengrab of the error). Then, when they try to take the survey again, it says their token has already been used. The good news is that their original response DOES get recorded, even though it says it didn't.... But this is creating some frustrated clients.....

More details:

I was able to reproduce the issues testing on a small scale survey. I tried importing from the old version as well as creating a brand new survey from scratch in the current version...

On the error messages. Here are the two that I have gotten when reproducing:

"The website cannot display the page
Most likely causes:
The website is under maintenance.
The website has a programming error"

Also there's this one:

500 Server Error
A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again.

More details:

So I tested the survey in another installation (Version 2.05+ Build 141126) and had none of these issues. I tested on an imported survey as well as a "created-from-scratch" survey. So is it possible that this is just a bug with Version 2.06+ Build 160123???

It is definitely very helpful that you could track it down a little. Although such 500 server errors are usually very hard to track down and fix.

Here is the changelog for the latest release:
github.com/LimeSurvey/LimeSurvey/blob/ma...cs/release_notes.txt

When going back into the past I see no potential fix at a later version so that problem may still exist.
So next question is: Which commit may have pasted this issue? maxersloan, you could help by checking at which latest version that was still working.

Here is a potential commit which is token related and may have caused the problem (hard to guess without checking all details):
-Fixed issue #10197: token in return link can be invalid after saving survey (Denis Chenu)

No,

It's just after save, you come back to a screen with a button 'return to survey' if the token have ~ inside : it's deleted. Very rare issue.

Thanks for your feedback, Denis.

Max, can you test if the issue still exists with the latest 2.5 version (first stable release is pretty new)?

If so, please create a bug report and post the link here.

Hi Mazi,
