I cannot open any child page generated by EE in 2 of my 3 sites which use Multiple Site Manager. Only my 'home site,' which contains all the EE system files, can open child pages. I have them listed below for reference:
Site 1, can open child pages: http://beta.autouplinktech.com (home site) Site 2, cannot open child pages: http://dev.autouplinkusa.com Site 3, cannot open child pages: http://dev.customerlifecycle.com
