'Add Subsite' Option Unavailable--Permissions Error?

Occasional Visitor

Hello, newbie here, 


I'm using Sharepoint Online. I need to add Subsites to my Sharepoint Site to organize it/set inherited permissions, etc. I have full control, including permission to create subsites: 


However, the option is not available from the Site Contents page:


Several colleagues also have full control and likewise cannot create one. I created a custom permissions group and specifically granted myself this permission again, but to no avail. 


Anybody seen this before? 


Thanks in advance!
