How to fix error/moodle/invalidsesskey

If you are running into the “Invalid Sesskey” error message, our experts are here to help.

In fact, this error occurs because our site does not have the PHP setting “session.auto_start=0”

This line is usually in the php.ini file. This line indicates that the session will start at load.

Let’s look at some of the common reasons that cause this error:

• The site does not have the following PHP setting:

  session.auto_start=0
• If we follow a bad link to a form script we will wind up with this error message.
• In case our database has an incorrect value for sessioncookiepath in the mdl_config table we will get the error message.
  This value can be modified in the Moodle config page.
• We may have logged out at some time between opening the form and submitting it.
• Additionally, if we edit the code in a file on the server while we are logged in to our Moodle website, we are likely to get this error message.

Furthermore, if you run into this error while running Moodle off a shared cloud server, we can proceed with these steps:

1. First, launch cPanel.
2. Then, head to Cache Manager.
3. After that, go to ByPass Domain, and enable the ByPass on our site. This will stop the site contents from being cached.

Alternatively, we can opt to disable our CDN cache.
