I have been having this issue with multiple EE installs since about 2.5.5.
Everytime I try to go to Accessories in the CP, I get a white screen with no errors. I tried turning debugging on in my index.php but get no errors output. Any ideas?
I have nothing except safecracker on my site right now, I uninstalled and deleted everything else that wasn't default (add-ons/extensions/etc) to see if that would help also. My cache folder & contents are set to 777 permissions, my accessories folder is 755 (haven't changed that). I have no idea why I can't access the page.
