The issue is caused because Archer now uses the "DELETE" method to the Archer RESTful Services API for deleting reports and this method may have been previously configured to be blocked in IIS.
There are several places where the "DELETE" method may be blocked.
Default Web Site location:
Archer Site Location:
3rd Party Module installed into IIS and used for Single Sign-On, Authentication, or Security Controls.
IMPORTANT: While Archer has security layers to verify the "DELETE" method is used safely on the Archer site, other sites on the same web server may not have such security, and may still require having the "DELETE" method blocked for security reasons.
