Hoping someone can help me with this. I'm running Odoo V12 CE. When I go to grant portal access to an existing contact (action>grant portal access), I get the below error. However, if I go on to our website and register a new account (sign in>don't have an account), Odoo creates both a new customer record and a related portal user account as it should.

Any ideas what could be going wrong? I'm not highly technical, so the use of simple words would be appreciated :-)

Many thanks in advance
