We are running DNN 7, and for the last several portals that we've generated DNN is creating a "image.png" file in the new portal's root. Also, in the <body> tag, DNN is writing an inline style of "background-image" that points to the "image.png" referenced above.
We've found the C# code in the Default.aspx.cs file that writes the inline style to the <body> tag - but we cannot figure out why DNN started doing this with new portal setups. We have setup roughly 150 portals in DNN the same way, but the last 5 or so portal-setups have been injecting this rogue image.png and hijacking our <body> tag.
Is there a really simple answer as to why it's doing this? Thanks!
