OpenCart Community

Hello,

If i access my stores admin url, or click on add to cart on the frontpage i get a popup with:

Error
Undefined

This happens ONLY if i access my websites without the www.

My websites are:

www.beleza21.com (OC 2.1.0.2) and www.kawibikini.com (latest version of OC)

Do you know how i can fix this?

Best regards,
evilfx

Yes.

To be serious, you should avoid the calling with AND without www
The error you have is based on this:

Quellübergreifende (Cross-Origin) Anfrage blockiert: Die Gleiche-Quelle-Regel verbietet das Lesen der externen Ressource auf http://www.beleza21.com/catalog/view/ja ... f2?v=4.4.0. (Grund: CORS-Kopfzeile 'Access-Control-Allow-Origin' fehlt).

Line 0

Hi Osworx, thanks for your reply.
Sometimes my browser auto-completes without the "www.". And then i get that error. I'm afraid my customers might see this error as well.

From your reply i didn't quite get it how i can fix it? Could you be more accurate as to what the fix is?

Is this something that happens to everybody?

Sory for outside of theme question, what is your slideshow called?
Is it aditional or it comes with theme? Please PM me when you can.

Fixing that can be done via 2 methods:

1. if you are using Plesk, simply define that there that you want URLs with / or without www (do not know if that can be done with other server panels like cPanel etc.)
2. simply add 2 lines to your .htaccess (either with or without www)

With both methods you are fine.

2. simply add 2 lines to your .htaccess (either with or without www)

how do i do this Osworx?

Sorry for all the trouble but i'm new at this.

To allow only non-www pages, add this here into your .htaccess

if i do that, i get the error all the time because it is without www. that i get the error.

i changed it to:

RewriteCond %{HTTP_HOST} ^beleza21.com [NC]
RewriteRule (.*) http://www.beleza21.com/$1 [R=301,L]

and now it is always www.beleza21.com and it works.

Thanks!

Important that it works.

While a 'www' is not really needed, it is just a subdomain technically.
So there is something else wrong.

HI Osworkx,

I m also getting same error for my new developed site ..
If i access my store and click on add to cart on the front page i get a pop up with:

Error
Undefined

This happens ONLY if i access my websites without the www. on mobile

My websites are:

www.kuchdeals.com (OC 2.2.0.0) and www.waydeal.com (OC 2.1.0.2)

Do you know how i can fix this?
Pls help

1. make redirect (with or without www) into your .htaccess
2. into config.php (main and admin folders) add or delete www. in "define('HTTP_SERVER', 'http://www.yoursite.com/');"

That's it in a nutshell. Cheers.

Hello,
Thanks for your conversation and observations but seriously I got solution from here, as I read that this is going because of www and someone said that www. is a sub-domain and that strikes in mind that yes, a sub-domain can be a issue as in some CMS the file paths are used according to the installation directory and its URL and thus, creates an issue with most common sub-domain i.e. www.

Well, making a permanents re-direct without using www helps a lot in case site is installed on without www directory and vice-versa in case of if site is installed in with www directory.
