      Thanks Toby, here is the entire HTACCESS file with your fix implemented. Doesn't seem to have worked if i go to

      http://atp-instrumentation.co.uk with no www it still fails to load

      Edited out to shorten convo

        Hmm ok,

        before i do anything else, we need to make sure that the .htaccess file is actually being loaded. To do that, we need to break it for a second.

        at the top of the htaccess file, put something like (specifics dont matter here)

        THISisInValid666

        What we're trying to do is put some invalid text into the htaccess file so that the site breaks when it loads. The idea being that we can confirm that the .htaccess file is actually being used. So if you put that in and the site throws a 500 error (when navigating to it with or without www) we can confirm that changes we make should work.

        If the site continues to load without issue then we know that the .htaccess file isnt in use so we need to look at server configureation directly (specifically the AllowOverrides settings)

        Once you have confirmed if it does / doesnt break, remove the line again 🙂

          Just a note here, the Redirects do seem to be working, so it looks like the .htaccess file IS being loaded.

          Please check anyway, its possible that the redirects are comming from another location if they have been set elseware as well. From a (very quick) look, the file seems to be formatted correctly so no obvious reason for the www redirects to not be working...

            I added the line and it did indeed break the website, got internal service error etc

            So it seems the file is working

              Ok, so the file is working, thats a good start!

              Looks like we need to go back a step in the request process then. Do you have access to the DNS settings for the http://atp-instrumentation.co.uk domain? If so, please could you check if there is an A record set for it? (looks to be registered through Civica UK Ltd - Whois Report)

              What i suspect might be the case is that you're missing an A record for atp-instrumentation.co.uk but that there is one set for the www.atp-instrumentation.co.uk.

              I've run a couple of tests against the domain DNS and i get nothing back for the non-www address, which is what suggests that we're not even making it as far as your servers.

              To set the A record, you'll be looking for something in your control panel for 'DNS settings' or maybe 'Host Records', you should see in there ether an option to select A record settings, or perhaps a dropdown with things like A, AAA, CNAME etc. You need to:

              • select 'A'
              • In the domain box type: atp-instrumentation.co.uk
              • In the IP box, type: 82.118.110.42

              Hopefully that makes sense. If your at all unsure, let me know and i'll do what i can to help more specifically. Domain control panels are so different for each provider its difficult to provide direct instructions without knowing what your panel looks like 🙂

                I dont have access to the DNS, my access is limited to the Magento CMS, and ftp access to the root folder.

                I guess its a case of popping an email off to the guys who built the site and control the web space and getting them to address the issue?

                  In that case that would probably be the best place to start. If you want any evidence for a missing A record, heres a DNS checking tool (it currently throws an error because it can't find an A record).

                  Let me know what they say 🙂

                        Glad to hear thats all fixed! Though i will say thats a very slow response time for any development / hosting company 😮 typically i would expect a maximum response time of 8 hours.. We try to keep it under 2 heh.

                        But yes, glad thats working for you now 🙂
