Yes I use tokens... is there a way not to use them?
I changed to "Use Cookies?" NO (there was in Yes)
and "Allow public registration?" Yes (there was in "No"
OK, sounds like you're a bit unsure about how the surveys work.
No, you _don't_ need to use tokens. Tokens should only be used if you wish to have a controlled list of invitees on your survey. If you just want to be able to publish a URL and have lots and lots of people do the survey, you _DON'T_ want to use tokens.
Once you turn on the tokens control, the only people who can do your survey are those who you have entered into your tokens table, with an email address, and who have had a unique token generated for them.
So, if all this is news to you, then I'd suggest your problem is that you've enabled tokens for this survey, but you really don't want them.
In the LimeSurvey admin, select the survey, then click on the picture of 3 people ("Activate/Edit Tokens for this Survey"

. Once you're in there, click on the document with a big red X through it (very right hand side) "Drop Tokens Table".. then click on the button "Delete Tokens". Then return to the main admin screen. Your survey will now be available to anyone who can click on the URL.
Then you should turn cookies back on, and you should turn off "Allow Public Registration".
If, on the other hand you wanted to restrict access to your survey to just those people you invite, then you need to turn the tokens on (or leave them as they are).
