I did look up this message before but could not find any detailed fix instructions and it was for an older version of the plugin and zen cart.
OPC 2.1.0 was working perfectly until I updated.
Updated to OPC 2.30

I am currently using...
Zen Cart V1.5.6c
PhP 7.2.26
Jquery 3.3.1
download products mostly-- Test Purchase was Free Download checkout

Do I need to update the Jquery? Which is so beyond me. Any help and suggestions is appreciated. Hope I have provided enough information if not I look forward to your questions to get you the correct information.
Just check F12 Console is showing these errors
SCRIPT1004: SCRIPT1004: EXPECTED ';' Index.php (175,876)
0: 'displayshippingblock' is not defined jQuery-3.3.1.min.js (1,31039)

I'm sure these are important but my limited knowledge of these things don't help. TIA
