Just a shot in the dark, do you have the add-on ''NoScripts'' on your browser? If so, you have to allow scripts so as to see those buttons. Best of luck
Thank you, sir. There is a switch in our preferences, somewhere, that activates the advanced editor; I've lost track of that simply because I've never really used it. I don't know if I even knew what the XenForo advanced editor looks like, except I must have, because at some point I remember setting my preferences to the simple editor, and haven't really thought about it, since. Even looking around my current posting screen, I don't see the option to activate the advanced editor, which in turn means it must be glaringly obvious.
Yes, I checked that before responding. Even with basic editor, I still see the Upload File link. My money's on Post Count Trigger.
I finally found a button; it's right there, if I am sending a private message. I don't have it on my editor for posting. Please Register or Log in to view the hidden image! Top: Moderator posting controls. Bottom: Conversation (private) message controls.
