I've actually had this issue for a little over a month, but haven't taken the time to bring it here, until now.
I have a page on my site which contains a gallery I regularly add to (weekly, for a web-comic I do), but the gallery widget placeholder that displayed when I edit the page in Visual is no longer there. The gallery still exists in the Text view, but I obviously can't access the gallery by clicking on that, as I was able to before in the Visual view. I tried adding another gallery, as a test, and I still have the same issue.. so it shouldn't be about just re-making the gallery anew.
My question boils down to this: If this is just how things are on WordPress, now, how can I easily access my already-established gallery?
The blog I need help with is markmushakian.com.
