A page failed to generate:
The queue keeps going and marks that one page failed, with the provider's error message shown on its card in the grid. Hover it and click Reroll. If a whole batch failed, go to the Providers tab and use Test Key on the provider you are using. An expired, mistyped or rate limited key is the usual cause.
Keyless pages look rough:
The keyless tier is a free community service and its quality varies. Adding the optional free key for it, or any premium provider key, improves line art quality noticeably. For books you intend to sell, this is worth doing.
Export fails or times out:
Building a 300 DPI interior holds a lot of image data in memory. The plugin already raises the WordPress image memory limit, extends the time limit and frees each page buffer before loading the next one, but a long full color book can still hit the ceiling on a very small shared plan. Options: export a shorter book, ask your host to raise the PHP memory limit to 256M, or move to a bigger plan. Coloring books and journals are far lighter than full color story books.
A provider was disabled automatically:
If a provider file ever breaks, the plugin quarantines that one provider rather than letting it take the site down, and shows an admin notice naming it. Everything else keeps working, and the quarantine clears automatically at the next plugin update, which is where the fix arrives.
The character drifted on a couple of pages:
Normal, and a two click fix. Reroll regenerates that page against the same locked sheet. To reduce drift, give the character two or three distinctive visual anchors such as a scarf, a spot pattern or a hat.
Where are my files?
The Publish tab shows download links after each export. On the server they are in your WordPress uploads folder, under rap-books, in a folder per book.
Why is the cover PDF missing from my export?
The cover is built from the project's cover art. If the project has no cover art yet, the export skips the cover step, returns a warning, and still gives you the interior, the digital PDF and the pages ZIP.
Still stuck? Open a support ticket and include the exact error text from the page card. It makes the fix considerably faster.
