I have a phpBB3 forum and I have a issue with my redirect from HTTP to HTTPS.
I am using in my .htaccess
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
Now everything works perfect besides the Login page , when I press on Login it redirects me to https://www.crowned.ro/ucp.php?mode=login , but my forum is located in /forum and for some reasons only the login doesn't want to redirect properly.
In this image you can see that if you hover over the Login button in the corner it shows the good link . http://prntscr.com/dojio3
If this happens to you too , check if the images has HTTP:// if they do change with HTTPS:// , because SSL requires every connection to be HTTPS:// in order to show up everything properly.
