Mentor error: Unable to accept mentor certification at this time (please help)

[Risvertasashi]

There's not much direct assistance we can offer. But:

- Double check each requirement on https://na.finalfantasyxiv.com/lodes...b5a39c/#mentor (Yeah, you mention you did, but just to be extra sure go over it with a fine-toothed comb)
-- Note that it's very possible to not have done 1000 dungeons, even if you have 3 jobs at max level, 300 commendations, etc.
-- Also note that if you've ever been suspended, you might not be eligible to become a mentor.

- Contact SE. You can try the tech support forums here, the main SE website, or the ingame support desk.
