[ic] Help required for stupid error

[ACforSale Inc Sales Team]

I hope this is possible to fix:
I accidentally changed the SERVER_NAME variable in the variable table to
include http:// at the start and now I can get into my IC at all,
running IC 4.9.6 on shared hosting with cPanel

When ever I try to login or use the store it comes up
http://http://..... this is driving me crazy as it now means the store
cannot be accessed either through admin or customers.

I can't edit the file variable.gdbm (which I think is where the problem
is)

Can anyone help me out on this
