'headers already sent' errors

[ardhill]

Hi,

I lifted the code and database backup from a ZenCart I had a few years ago, and am trying to move it to a new server.

The ZenCart version is 1.3.7

I have taken my back-up of the code, altered the config files for the new server and added a back-up of the old database.

I haven't upgraded, just trying to get that version to work right now.

I have ironed out a couple of glitches, but, I still have a problem, I am getting the following errors at the top of my catalog pages:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/SiteFolder/public_html/includes/functions/extra_functions/pawel_attr.php:89) in /home/SiteFolder/public_html/includes/functions/sessions.php on line 108

Warning: Cannot modify header information - headers already sent by (output started at /home/SiteFolder/public_html/includes/functions/extra_functions/pawel_attr.php:89) in /home/SiteFolder/public_html/includes/init_includes/init_templates.php on line 78

I don't know how to fix them.

Can anyone help me please.

ZenCart version 1.3.7

Thanks,

Paul

I have now discovered also, that if you try and add a product to the cart, you get a blank page and the following error messages:

pawel_attr.php doesn't exist in a stock Zencart installation. It must have been part of a mod, so we don't know what line 89 says.

Also, unless you had a lot of custom work done on the old site, I would consider starting from scratch, using the much more secure current version.

That's great thanks, I appear to have sorted it with the help on that page.

I do intend to upgrade it. But, It has a fair bit of custom work done on it, and I didn't do it myself. So, I wanted a propry working copy to start with, so I could figure out what changes had been made, so I could do the upgrade.

Thanks for your help.
