TMC security error message when I try to post a .PNG file, no problem posting .JPEG

Thread title says it all.

“Security error occurred. Please press back, refresh the page, and try again.”

This started happening for me yesterday afternoon, in multiple forums.

Just tried to attach a screen capture of the error message, it’s a .PNG file. This time I did not get the security error message and the screen capture looks like it will properly display in this post. But a few minutes ago I could not post a screen capture in the SpaceX forum.
