Hello, I want to mention that I have conducted extensive research on the error I am about to discuss. While some people attribute it to the SSL certificate, others have been unable to provide a clear answer.
Here is the issue I am facing:
I have developed a relatively simple API to connect the form I created using Kodular to my online database. I tested the API using Postman, and it functioned properly. However, when I attempt to submit the form data, I encounter the 1103 error.
Have you tried using some of the suggestions given as a solution here in the community?
The POST sending is ok, what about the return? Have you tried putting a var_dump($data) or $json and die() in your script and checking what the error is?
