Security Token Error Message

Cheryl Schmelzer

What does it mean when this message appears after attempting to save an updated page?

"Your request could not be processed because a required security token was not present in the request. You may need to resubmit the form or reload the page."

When we do save the page again, not all changes are applied.

This occurs intermittently. Can somebody tell me what might cause this error?

Thank you.

Hi there,

First try to flush the browser and check if this issue will occur in different browser. It is possible that this issue is related to this bug https://jira.atlassian.com/browse/CONF-23148

According to the bug report, this issue might be caused by Apache/Tomcat configuration. Below is the comment taken directly from the bug report:

We discovered it to be a bug in the Apache/Tomcat configuration.

This issue crops up when using Apache 2.2 (and possibly 2.0 with mod_jk), and is due to the Apache config variable ProxyIOBufferSize (for 2.2, not sure what it's called in mod_jk) having an undefined size.

By adding "ProxyIOBufferSize 8192" to the vhost connected to the Confluence instance this problem goes away.

This has to do with how transfers between the Apache and Tomcat instance gets chunked up and buffer use, and fixes similar problems in other projects I work on, too, such as OpenNMS with an Apache front.

Untill Apache 2.2.14-ish "ProxyIOBufferSize 16384" would also work for more efficient transfers, but recent doc changes at apache.org vaguely states it has to be set to 8192 or less. The default is stated as being 8192, but does not work, explicityly defining it fixes the problem.

You may want to update your apache configuration to include the ProxyIOBufferSize setting to see if this fixes your problem. If you still have problems please contact our support team at support.atlassian.com

If the issue persist, please contact our support team at support.atlassian.com as suggested.

Hope this helps!

Kind Regards,
