Hi @Dalphine Hicks27! If you're an admin, you should be able to edit Questions posted by yourself and other members.
If you're not an admin, you can only edit your own Questions. It's also worth mentioning that when a question receives its first answer, as a regular member you won't be able to delete or edit the question. In this case, you'll need to contact a community admin to do it for you.
If this is not the case for you, please contact us directly via chat or email22 so we can investigate further.
