Question

I modified the example script from the Plesk documentation to create an A-Name Record remotely, but gave up on it weeks ago as it was nothing but headaches. I have now started working on this again, but am now faced with the exact same problem. The example script comes filled with try/catch and error exceptions, but no matter what, all I get is a white page when I run the script.

I tried adding a bunch of echos to the document as well, but unless these are outside of the functions, they do not print out either. Am I just doing something very stupid or is there something I am missing with Plesk?

Thanks to rdo’s comment, I was able to determine that it would not accept “domain_name” and instead wanted a “site-id” instead. Once this was used, my script worked flawlessly.
