We are website builder company and we recently received complaints from our users that their card stopped working.
Here is one example: https://www.hotelscheapbooking.com/
The user didn’t change anything recently and he said it stopped working in the past 2~3 days. While the error message shows that the content is too large, I saw it is only 66kb in chrome for the HTML payload. I’ve read through this thread and checked all the possible causes: Not Whitelisted, unable to render, or no image: READ THIS FIRST.
Please someone help me here.
