Please help, I get the error: error undefined

this pops up in an alert box when I first login to admin or attempt to purchase something from the store

Hey Jarv,

I had the same problem with Opencart V2.2.0.0 when I click "add to cart". the error message pop up

This site says
Error

Have you solved the problem? Thank you.

Hello,

For those that still have this problem here is the most likely solution:

1. Check the URL:
- try accessing your website with and without WWW in the URL. Example: http://www.example.com and example.com
- if you discover that the problem is caused by the URL keep in mind in what situation the problem appears (with or without the www)

2. Edit .htaccess
- log in to your FTP client/CPanel -> File Manager and go to the root of your website (public_html or similar)
- if the problem appears when you have www in front of your store's domain (http://www.example.com), follow the instruction in point 2a
- if the problem appears when you DON'T have www in front of your store's domain (example.com), follow the instruction in point 2b

2a.
- copy paste the following code to the bottom of the file*:

#Force non-www:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.example\.com[NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

* make sure that you edit the example.com link to suit your actual domain name

2b.
- copy paste the following code to the bottom of the file*:

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

* make sure that you edit the example.com link to suit your actual domain name

3. Hit save and check if the problem is solved.

Thanks SporeD3v.

Hello, please help me.

I have an some error when ordering products on the site uleiulesential.ro, when sending a message, when trying to create an account.

I have opencart 3.0 theme Journal.

Could it be because we changed the domain name from do-terra.ro to uleiulesential.ro?
Thanks,
Best Regardes
