I am a freelancer / web developer. And hence am trying to integrate the WhatsApp chat widget on one of my website.
I am registered as free member for now. Created a WhatsApp widget. And added the generated script to my PHP web page but I do not see any chat window popping up. I think I am missing something.
In this case, the issue was just a cache problem.
The PHP website was not refreshing the Script added into the template. Just to be sure you are seeing the latest version of the script, open a new window with incognito mode on, or just open a new browser.
