I'm using gift certificates as an example; I should have gift certificates for $25 $50 $100. It shows in the admin:



But not on the catalog side:



I have this error log, but I'm sure what to make of it.

Appreciate any help, thanks!

I do see all 3 gift certificates in "All Products" and "New Products". But only 2 when I go to the gift certificate category

The 2 GC's that do display in that category have been created as Product Type "music".
The other 1 that's not displaying in that category is Product Type "general".
(I can tell this from the URL that's used to display each of those products.)

If you edit that category in your Admin (using the "e" icon on the button bar next to the category, so that you can edit the category's name/description), do you also have that category limited to only "music" product-type products?

It's always something so simple

The missing one should have been in music type and this is indeed a category limited to only music products.

Thank you!
