Lost Network Admin Password

Hi,

I am somewhat new to this.

I did have access to add/delete plugins but then the Add Plugin button disappeared. I read here that this can happen if you have a Multi-site account. However, I only have one site. I also see that I do have a key symbol and a Network Admin menu at the top. When I try my same password here, it does not work. I also do not have a Network Admin tab on the right where it says, “Howdy Alysha”. I read that this should be there if I have a multi-site account.

I tried the “lost password” button but it returns the message that there is no one with that email registered. What other options do I have? Is this something my hosting company did, or did I do something wrong?

How do I get in there to add plugins?

Thank you,

Aly
