WP Odoo Form Integrator

[swtlinor]

I tried connecting the WP Odoo Form Integrator plugin to my openerp7 (Odoo7) and i keep getting this below error message on WP Odoo Form Integrator Settings when i click on TEST AUTHENTICATION.

Traceback (most recent call last): File "/opt/odoo/adun2/openerp/service/wsgi_server.py", line 81, in xmlrpc_return result = openerp.netsvc.dispatch_rpc(service, method, params) File "/opt/odoo/adun2/openerp/netsvc.py", line 293, in dispatch_rpc result = ExportService.getService(service_name).dispatch(method, params) File "/opt/odoo/adun2/openerp/netsvc.py", line 118, in getService return cls._services[name] KeyError: '2/common'

Please help.
Thank you.
