A new zip 03-21-2016 has been posted, which includes the following fixes:

a) zc_install when upgrading configure.php file contents, was assuming SSL was enabled, and accidentally enabled the ENABLE_SSL, ENABLE_SSL_CATALOG settings and set the Admin HTTP_SERVER to the old HTTPS_SERVER value. It now reads the old settings more intelligently.

b) zc_install was running into SQL schema problems if the old data had zero-dates in previous fields in the admin table. It now attempts to fix that data first.

c) zc_install has now been updated to auto-insert 3 old configuration table entries that sometimes got deleted by old plugins containing incorrect install SQL code.

d) zc_install was not properly honouring table-name prefixes during some cleanup phases of the db-upgrade process.

e) The Admin english.php file was updated to add a missing define for TEXT_PRICED_BY_ATTRIBUTES, which was only a problem on the admin screen for copying products between categories (ref: Missing english definition for products_to_categories):

/admin/includes/languages/english.php:
Code:
  define('TEXT_PRICED_BY_ATTRIBUTES', 'Priced by Attributes');
