OK, I have looked through years of posts with people having the same issue. Scenarios can not seem to be created on Wordpress without a 403 error. I have tried it on my site with siteground.com and with my site on onios.com. Both sites yield the same error. I have checked file and directory permissions, .htaccess files, reissued API keys by deleting and reinstalling. Nothing seems to work. How can this issue go on for YEARS with no sulution? If you have a solution, please post it. Save your breath however is your answer is the same tired excuse of “without access to your server.”
Welcome to the Make community!
Can you please share the full error message here, as well as relevant screenshots or video recording of how you are setting it up?
