Hi kamlainda,
Upgrading from Joomla! 1.5.x to Joomla! 3.2.x AND from SEBLOD 1.x to SEBLOD 3.x ... is not something easy.
As you may know there was a huge gap between these versions.
I would suggest to use the following tools to export your content from SEBLOD 1.x.. and then import them on the SEBLOD 3.x site.
Old exporter add-on:
documentation and download here.
New importer add-on:
product page.
Regards,
Saba.
PS: from Joomla! 2.x to 3.x AND SEBLOD 2.x to SEBLOD 3.x ... you can update with only a few clicks, and of course some verifications.......
