“No 'access-Control-Allow-Origin' Header Is Present On The Requested Resource”

[zinor]

Hi 

i got this error when editing products in BO .

 

index.php?controller=AdminProducts&id_product=958&updateproduct&token=769e254……:1 XMLHttpRequest cannot load http://www.mydomain/index.php?controller=AdminProducts&toke…action=Attachments&updateproduct&ajax=1&rand=1457345318849&_=1457345310680. The 'Access-Control-Allow-Origin' header has a value 'http://mydomain.com/' that is not equal to the supplied origin. Origin 'http://mydomain.com' is therefore not allowed access.

 

can anyone help me ?

thanks

You should make sure you connect to the backoffice using the EXACT URL defined in your Preferences->SEO&URL page

 

If it's defined with www. then you must use www.xyz to connect to the backoffice

i did that but without any change .

in fact in the seo & URL page i used www. but in the BO without www. so i used www. in the BO but without any change !

also i deleted www. in that part and connect to the BO without www.  but without any chance .

As you can see, the site is trying to make a call to www.mydomain, look for where that call is made, and make sure it uses the correct URL
