Error When Choosing PHP 8.0

I am running v.1.5.8a and have updated my PHP to version 8 to accommodate an upgrade to Zen Cart Version 2.0.1

When I changed my PHP version from 7.4 to version 8.0, my live site (Zen Cart v.1.5.8a) now throws the error: Undefined variable $flag_show_product_info_tell_a_friend in templates/custom/templates/tpl_product_info_display.php on line 214

Not sure why its doing this as this is same coding in Zen v.2.0.1 that is on my local computer that I am working with to upgrade and I'm running PHP 8 on there.

Thoughts???

Thanks,

Jeff

There's no setting or use of the $product_show_product_info_tell_a_friend in the as-shipped Zen Cart 1.5.8a release.

I'll suggest that you modify your custom template's tpl_product_info_display.php (on/around line 214) to remove that legacy value's usage.

Thanks lat9 for your reply and to let me know about this dated file I have in my store. I will remove this!

Thanks again for your help!

In upgrading my current site from v.1.5.8 to v.2.0.1, we have a larger store with a huge images folder, downloads, etc. where I normally (after updating custom files, add ons, etc) upload the new Zen Cart version to a newly created folder on my server to run several tests on it before taking it live.

What would be the best way to install my customized test version of v.2.0.1 on my server as I need PHP 8 to have it run, but running my current v.1.5.8 it throws errors and the downloads do not work.

Thanks in advance for any suggestions!
