I have a WP blog at https://example.com/blog. I’m able to access the wp-admin pages but the front-end pages are messed up (https://example.com/blog/page/2/). I have /blog set as an alias in my Apache VirtualHosts configuration file. It was working fine before I switched on HTTPS through Cloudflare.
