Recently our site was hacked; the support guys have said it was 'rt_solarsentinel_j15' template that had the vulnerability. I have asked them for more information about this and I will post in here once I have that info.
I was using the latest version of this template so I am wondering if there was something else I didn't cover that lead to the issue. The support guys have removed the template and I'll be needing to get the template back; but wanted to make sure it wasn't going to be insecure again when it goes back up.
