You used the https:// inside your src attribute. I was just thinking about if that could have been the issue.
Here’s my thoughts:
It could be either that the image is actually loading, but somehow the formatting is messing up, OR the image is not actually loading at all.
I would try testing the latter first by using the alt attribute. Set alt = “my_image_txt” and see if the same white box referred to shows up, or if the alternate text shows up.
Does your src attribute need to be closed with a quotation mark?
Right, that’s what I have been using to search for one. I cannot seem to find one that comes pre-integrated with Square/PayPal. Rather, Square seems to be a paid add on gateway for every plugin I have come across.
