Access denied to all users after migrating site to new server Please don't consider this as a duplicate post. I have tried all the solutions that worked for others, but still struggling to fix the problem (all users including admin taken to 403 page). This is a Windows server running Drupal 7.

Things I have tried -


No base_url value given
No cookie_domain value given
Session table truncated
Cache tables truncated
No file permission differences
Tried Reset password email but the link takes to 403 page
Deleted browser cache


Please let me know if anyone has experience with a similar issue or what else I could try.

This is what I can see in watchdog table.


Thanks
I finally figured it out!

We are enforcing secure flag on our cookie and therefore had to disable the corresponding rewrite rule from IIS, as we didn't have a SSL certificate in new server.
