Response not JSON!

[AndyB]

I recently changed my server to HTTPS. One of my add-ons has a button that links to:

https://www.southbayriders.com/forums/rsvp/register?t=154761

In the PHP code I have the following where I want to assign the the variable $threadId by getting the value of 't' from the URL.

// get threadId from URL
$threadId = $this->_input->filterSingle('t', XenForo_Input::UINT);

If I put an echo $threadId code directly after this PHP code I get the following error when I click the button.



Does this have anything to do with the HTTPS I'm now using?

I'm just curious here, does that button fire any JS?

No JavaScript is being used.

Turned out to be a corrupt XML file. I needed to uninstall the add-on and re-install from a backup.
