I face the problem of Invalid input condition error on sign up while using currencies other than INR (Default Currency). When my client registers keeping INR his currency, everything goes Ok. But when currency is changed, it shows "invalid input condition".Please help.

Hi,

This could be caused by a custom action hook/module. Please try removing any customisations from /includes/hooks and /modules temporarily and try again.
