LNBits - Unable to install extensions

when I log in using the AdminURL I see “manage extensions”, but no extensions are displayed. What can I do?

Umbrel: 0.5.4 / LNBits: 0.10.6

There seems to be some extra instructions in the Umbrel appstore for LNBits- does this help?

Yes, I followed the instructions and logged into the “Super Admin page”. But no extensions are shown.

Sorry mate, not sure then.

Outside of the above, all I can recommend is the classic IT fixes if you haven’t tried them.
Cmd + Shift + R or Ctrl + F5 for a hard-refresh
or even

sudo ./scripts/app update lnbits
