Hi all,

After I updated taxonomy_update.module I observed that a blank screen would occur when using the radio buttons to activate or deactivate the taxonomy_access module. Function was not impaired and the module was being activated or deactivated as requested.
Using the back button on the browser allowed workflow to continue and no other consequences were manifest.

The log entry showed:

Location /caa/admin/settings/taxonomy_access
Message warning: Cannot modify header information - headers already sent by (output started at /home/james/public_html/drupal/modules/taxonomy_access/taxonomy_access.module:568) in /home/james/public_html/drupal/includes/common.inc on line 155.

I identified the cause of this error to have been trailing spaces in the taxonomy_access module beyond the the ?> tag. These had been introduced by me because I cut and pasted the source from cvs when I could not find the file download.

Lesson learnt, problem fixed.
