Hello,
I had the exact same problem when i try to upgrade to wordpress 4.6 ( i am using the theme Rosie from free vision). My website is working in home page url and other urls. However i was not able to access my Admin page (https://www.kidswallpainting.com/wp-admin). It gives the following error
Fatal error: Call to undefined method Requests_Response::is_redirect() in /home/content/83/10792583/html/riot/kidswallpainting/wp-includes/class-requests.php on line 685
tried the following.
1. Manually resting the plugins by renaming the plugins folder to Plugin.hold. But this did not worked.
2. Tried downgrading the WordPress to 4.5 Version as per instruction. But still getting the same issue in the admin.
Can someone help me out this ?
