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.
