Hi there,
I'm having this exact same problem. The Terms & Conditions popup appears, but there is no text displaying (I have selected the correct article in HIKASHOP > CONFIGURATION > CHECKOUT > TERMS AND CONDITIONS).
I'm using Joomla 3.5.1 and HikaShop Business 2.6.3.
In my case, I am using a custom template, and the problem ONLY manifests when I am using that. Everything is fine when using the Beez3 template - but I'm not sure how to get to the bottom of the problem, or why my custom template is not allowing this to work.
For what it's worth, the GENERAL DISPLAY OPTIONS are set as follows:-
Use bootstrap design: No
Popup mode: vex
Use Chosen library: No
... changing the popup mode to any of the alternatives does not seem to make things work.
In the general Joomla config, GLOBAL CONFIGURATION > SERVER > ERROR REPORTING is set to 'Development', but no errors are displaying on the Checkout page or Terms and Conditions popup (it remains blank). Error messages do seem to display fine, in other situations - so error reporting seems to be functioning well in general.
You mention in your previous message that I can change the code in the 'terms view file' to make the Terms and Conditions appear on an external page - but I don't know how to find the terms view file you're referring to. Can you point me in the right direction, or otherwise advise further?
Thanks in advance.
