Hi Heath, thanks again for your quick response and for hopefully solving the issue so quickly! :D
about the widget on multiple pages, I didn't quite understand you -sorry, maybe as english is not my mother language-. I'll try to explain quickly my process:
In my theme, the left and right sidebars, and left-subpage, right-subpage sidebars are split into 3 sections each, all 6 sections are identified in the Widgets page in the admin as:
- "Over left",
- "Over right",
- "Over left subpage",
- "left-center subpage",
- "bottom-left subpage",
- "Over right subpage",
- "right-center subpage",
- "bottom-right subpage",
(Subpages: all posts, pages, archives, search)
In all of them I can add as many widgets as I want, native to WordPress, to the theme, or by plug-ins (of these I have 2 or 3 more, like "My Catergory Order" plugin that creates a widget, same as "FlexoArchives").
So, I added "My Category Order" in "Over left", and "Over left subpage", without any problem. Then I added FlexoArchives in "Left-center", and then tried to add it to "Left-center-subpage" and it was gone from the window (or area) "Available Widgets".
So far has been the only widget with that behavior. I made an extensive search in google, and ended here asking you directly.
Hope it is clear what I exposed before, and hope it can be solved.
Thanks again for all your understanding and help to solve the issues and of course your dedication :)
