Bwah,
did a full reinstall of osCommerce RC2a including the Ajax Attribute Manager, FCK Editor, QT-Pro, Ship2Pay, Ultimate SEO, Ultra Pics, Simple Template System and the Master Products Module (took me almost all night ...).
Everything works except .... Master Products.
With the Master Products added the simple template is not working properly anymore (suddenly the files are only parsed to half way the file), I get some extra fields for free (that are not part of Master Products) and the attributes that I add to products do not show up in my shopping cart.
Also, 'slave' products do not appear as separate selectable products in the catalog but they do show up in the "new products" window - from where I can select and buy this as a separate product.
I a sorry but it looks I have to tell the customer that I have to remove the whole Master Products module and search for another option. There are just too many problems with the Master Products module to solve for me.
A whole week of data entry lost ...
