The homebrew creator for D&D Beyond keeps displaying the following message for the ranger subclass I created: 

This Subclass cannot be shared with the community for the following reasons:

• This homebrew Subclass does not have the necessary class features with the correct required levels.

However, the subclass I created is not missing any class features for levels as far as I know, I have class features for levels 3, 7, 11, and 15, as expected for a ranger. I would share a link to the subclass causing the issue, but I can't share it for obvious reasons.

You can post the link to it, a mod would be able to take a look.

My question is: do you have any Ranger subclass features at levels other than 3, 7, 11 and 15? Those would also prevent publication.

But we strongly recommend not publishing any homebrew until you've had a chance to check it over thoroughly, make sure it looks right when used on a character sheet, and playtest it. Once you publish a homebrew, you can't Edit it anymore.

In addition to what naruhoodie posted, please see the General FAQ #Ω for answers: (https://www.dndbeyond.com/forums/dungeons-dragons-discussion/homebrew-house-rules/131411-a-homebrewers-how-to-faq).

Oh, I see then. In that case, I'll put the link to the homebrew here.

I'm definitely sure I didn't put any other features aside from those at levels 3, 7, 11, and 15. I'm wondering if it might have to do with the fact that there are two level 3 abilities? I'm not sure, so I'd love to know.

I'll also check out that FAQ as well.
