HI Mohamed;
Yea, sorry, but the problem with your work around is that it doesn't address my problem.
You see, the UPS plugin > Warehouse section > Zone edit,
works almost identically to this other plugin I have : Ed Canada post plugin by WyldCode,
where I have the exact same problem.
And I need it to work, as the plugin absolutely needs it in order to give me an accurate price.
I am in contact with WyldCode, but as the problem is also present in the UPS plugin, he claims it has something to do with Hikashop.
So I've been communicating with both him and you to get a solutions, but so far no luck yet !
Switching to the VEX popup didn't help because Squeezebox is hard-coded into the anchor tag of Zone > EDIT link.
So change it to VEX all you want , nothing changes.
I guess what would be nice is if the warehouse section > zone edit would be able to function using whatever popup you choose in Hikashop Configuration > Display > Popup settings (like all the others).
Or somehow get Squeezebox to work ?
It's a mystery why Squeezebox doesn't work for just that instance, as it works on all other Zone areas on the same page.
My guess is: Maybe the javascript is returning a string that Squeezebox cannot parse (instead of an object).
No sure... It just a wild guess, based on the output which appears to be a sting (in the popup)??
Help.
