Your site is not reachable right now, although I did manage to check out the links briefly this morning on my cell phone while waiting on breakfast to cook.
I think you are mistaken in the way you must have had it set up before. From the page that you said was not working, it looks like you tried to put the shortcode for that include page plugin inside of the text editor that you use to create the description for the sheet, as it was showing up below the sheet title and contact info.
If that’s what you are trying to do, then that will NOT work, and it has never worked that way. A sheet is not a page or post, and it’s not displayed with a WordPress template, and none of the “content” (the description) is run through any of the normal WordPress page or post content filters. So, there is nothing in my plugin set that would process the shortcode from another plugin from inside the description for the sheet.
That sheet description is stored in my own custom database table for the sheets, and is saved as html. The text editor was only put there to make it easier for people to format the description nicely, but it is NOT a page or a post, so you can’t insert shortcodes from other plugins in it.
More than likely, if you had this working before, it was because you had the insert pages plugin shortcode above or below the signup sheets shortcode on the actual page where you are displaying the signup sheets. It would never have worked inside of the description for the sheets themselves.
This is not a “bug” that I can fix, because it was never a feature of this plugin. Feel free to post it in the feature requests section of my web site. Otherwise, if you want the content from another page posted within the description for a sheet, then you need to actually copy the content from that page, and paste it into the text editor for the sheet where you want it displayed (again, no shortcodes will be processed, so it all needs to be html).
