I have a problem that after installing Stock by Attributes of version 4.7 (also in 4.6) in Zencart version 188.8.131.52 I got an error message during order process. The message is:
Fatal error: Cannot redeclare class order in /home/www/slune.eu/subdomeny/www/includes/classes/order.php on line 1069
Can you give a hint where can be the problem? I guess that the problem can be some conflict with some other contribution. I have the following add-ons installed: Printable Pricelist, Edit Orders, Easy Populate, Image Handler.
