@riversworldsa –
It looks like something is automatically adding that /ar/ to your shop URLs. If it’s not in your settings, I suspect it’s a plugin.
Can you please confirm that you don’t have this entered anywhere on the Settings > Permalinks > Product Permalinks or in the section above it for “Optional”?
Additionally, are you using any sort of redirect plugin or any plugin that might effect your URL structure?
As grigaswp suggested above, you really need to conduct conflict and theme testing. Until you’ve taken that step, we cannot really help you with the issue because we need to rule that out first and foremost.
Here are the steps we need you to take next:
1.) To begin, please make sure that your theme and all plugins are up to date.
2.) Try to deactivate all plugins except for WooCommerce to see if the issue persists. If the problem goes away, re-activate and test each plugin to see if you can determine which plugin the problem originates from.
3.) If the above does not resolve the issue, try switching your theme to the Storefront theme (https://woocommerce.com/storefront/) and see if it works correctly. If it does, you’ll want to contact your theme’s developers and see if they have a fix/update.
If the above steps don’t resolve the issue, please feel free to send us your System Status Report to help us troubleshoot. You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, you can paste it into your reply here.
