Thunderbird Profile cannot be loaded
When I try to open Thunderbird (using my normal user account), I get the message:
"Your Thunderbird profile cannot be loaded, it may be missing or inaccessible"
But when I switch over to the admin account- I can open Thunderbird
I'm not sure how to fix this, could anyone please help?
macOS version: 10.13.2
