From BPS security staff - I downloaded the Boot Store Theme
I downloaded the Boot Store Theme and the php error is exactly correct. This function tcp_the_currency() is not defined/does not exist in this Theme:
The function is being referenced in this variable in this file: loop-tcp-grid.php on line 47 and in a couple other files in this Theme, but the function does NOT really exist anywhere in the code of this Theme. Contact the Theme author to have him/her fix this.
$currency = tcp_the_currency( false );
