The page warnings about the margins being exceeded means that the content on the pages is outside the print safe margins. You have a few options:
a) You can edit the content down so that it fits on one page.
b) Split the content up and place it across two pages.
Unfortunately, our software does not currently support a single recipe spanning multiple pages.
In cases where our software is reporting false errors, try opening the Edit Recipe dialog, and without making any changes to the recipe, click on the blue Save button. In a lot of cases, this will eliminate the warning if the error is falsely being reported.
A good general rule is that if your content is above the page number then your content should be safe. Make sure that if you've added a recipe or photo to a recipe page that you make sure the content doesn't spill over into your additional content.
The best way to see if your content is overflowing is to generate your print-ready proof files. Our software can sometimes be a little conservative with calculating if content will be safe or not. The print-ready PDF will show you the exact layout of your contents as they will be printed for each binding style.
