Edit: I have only just taken over management of this part-completed site, which was copied over from shared hosting install to a VPS. Some configuration might be slightly wrong - I'm not sure, yet

Update1: I seem to have fixed the looping 'Access Denied' problem. The .htaccess, shown below, was in public_html/ but seems to have been created by Front Page. There was an additional .htaccess in public_html/temp/ (where Drupal is temporarily installed). Adding RewriteBase /temp to that htaccess fixed part of the issue.

I seem to be getting some sort of loop happening on my Drupal 7 installation.

Occasionally on basic pages which don't require authorisation I get multiple lines of 'Access Denied: Please login' . (see Update1)

Pages that are restricted to authorised users should redirect non-authorised (anon.) users to login/register - but at the minute it fails with a redirect loop (ie: if I visit {domain}.co.uk/admin before logging in I fail with a redirect loop).

Also I seem to be having a problem switching between https and http pages. - I think this is the main issue

Here are some details:

  • SSL configured for www.{mydomain}.co.uk
  • Site does not rewrite {domain}.co.uk to www.{domain}.co.uk
  • Module: URL alias disabled (until fixed this)
  • Module: URL rewrite disable (until fixed this)
  • Module: SecureLogin was installed but now disabled.
  • (update) Module: Ubercart SSL causes 302 on ALL pages (may be relevant)

  • Try going to admin/reports/status/rebuild and rebuilding all permissions. – Bisonbleu Mar 27 '13 at 13:03
  • I have just rebuilt the permissions and am still having the same problem. – kaipee Mar 27 '13 at 15:57
  • I seem to have fixed the looping 'Access Denied' problem. The first .htaccess was in public_html/ but seems to have been created by Front Page.

  • UPDATE: there was a custom 403 page (which I had no idea existed previously) which was causing redirect loops. I have updated the PHP code which now correctly redirects to a login page. The only problem I now have is switching to HTTPS and back again (currently loads my new 403 page) – kaipee Apr 4 '13 at 9:42
