I just updated from EE 2.5.1 to 2.6.1, and now I get a redirect loop error when I try to access the control panel via admin.php
.
I cleared my cookies (and started testing in incognito mode to be safe), cleared my .htaccess file, and I added cookie variables to Master Config:
$env_config['cookie_domain'] = '';
$env_config['cookie_path'] = '';
$env_config['cookie_prefix'] = 'kg_' . ENV;
But that didn't fix the problem. What else should I try?
