Install on Joomla 1.5.23

-- HikaShop version -- : 2.2.2 Business
-- Joomla version -- : 1.5.23

Hi, I am trying to install Hikashop on our secondary website which runs on the older joomla 1.5.23, I see it is compatible with Joomla 1.5. Although, when I select "upload and install", it goes to a blank page called /administrator/index.php and doesn't do any installation, what could I be missing please?

Thanks
Alan

Hi Alan,
Like it's said on the documentation :

A blank page does not help us to determine what could be the problem so if you get a blank page (an entire white screen without anything written on it), please make sure that your PHP configuration enables you to see errors and if not, edit your php.ini file and search for the string parameter display_errors.
This parameter should be turned On : display_errors = On.
If it's not the case, please edit your php.ini file, modify this line, save your file and then restart your server and try again to install HikaShop. You should not see a blank screen anymore and the error message will help us a lot to fix the problem.
If you can not see any error, please try to install HikaShop via FTP, it solves more than half of the installlation issues.

couldn't get the errors to display but SOLVED it anyway.

Repackaged the install file as a ZIP instead of tar, worked straight away.

Thanks
Alan
