Errors Occurred While Making Your Changes - DIsplay Network Placement Exclusions
Right now I am unable to add URL's to my display network exclusions list. Using the web interface when I view my placements and check the box to add URL's to the exclusion list and select the "Exclude (campaign)" option I get a small popup at the top of the screen saying:
"Errors Occurred While Making Your Changes"
As a consequence my ads are now being displayed on sites I don't want them shown on. Fix suggestions please?
