Thanks a lot..you made my day... that was easy...don't know what could have caused problem and never thought, it would be that simple, as thought some serious problem.

Can there be some remedial or back-up method in future, (even after testing ) whereby if happens to live site, errors can be corrected immediately, so that atleast Site is Live for visitors

Also, What is best method to upgrade abantecart

Thanks a lot once again

Regards
Pankaj
