Intermittent cache issue

I'm periodically seeing the below error in the PHP error log. It's intermittent, and it only seems to occur when a user is editing content on the admin pages. The user tells me the error ("Cannot modify header information") usually clears on the next page load.

Looks like the code is looking for cache content but it's not there.

Any ideas?

Code: Select all
