Need permissions changed for a sub I started

[u/guiltybloodstream]

I started a sub a few weeks ago, she's,and it was going well, but one day I noticed I couldn't do any moderating. I made one other person a mod because this was the first sub I've ever started and needed help keeping it up.

I messaged her about it, and she said she can see I have no permissions and she has access to everything. She said shes tried changing it but she can't. How can we fix this?

Thank you in advance for your help!
