Hi Dennis

I am experiencing the same / similar problem "Bad Request - The CSRF token could not be verified"
The problem is that my client is experiencing this intermittently when submitting pages. (which generally has less than 10 answers on)
We also don't get the problem on the same page.

From 1200 people, 350 completed successfully and only 35 complained about the error.
The problem however is that it is still a significant amount of people.

Please can you give me a idea what I could look for, or how I could go about troubleshooting this problem?

The survey uses TOKENS
Allow multiple responses or update responses with one token = NO
Enable token-based response persistence = YES
We are using Version 2.05+ Build 140618

Surely some session issue ?

1st idea: uncomment the database session example in your config.php
2nd idea : Disable CRSF validation : manual.limesurvey.org/Optional_settings#Request_settings
