I am having trouble getting a redirector page to point to a page with a # anchor on the end. Every time I add a link and click Save it empties the field. If I just point to a direct URL it stores it fine. Does this sound like a bug or am I missing something?
It was the Cyber-Duck/Silverstripe-SEO module. I had to uninstall it because the SEO button in the CMS left hand menu caused an Internal Server error (500).
