Missing Page Information

[chrxbhj]

Hello All.

Having a problem with this site:
https://harmonicdampers.com/

Observed issues...

Home Page:
Nothing appears below define_main_page file text. Categories should be showing:
https://harmonicdampers.com/

Category Pages:
a.) Nothing appears below category name for categories that contain sub-categories:
https://harmonicdampers.com/index.ph...=index&cPath=6
b.) Normal appearance for categories with no sub-categories:
https://harmonicdampers.com/index.ph...dex&cPath=6_66


Product Pages:
a.) Nothing appears below main product photo on some:
https://harmonicdampers.com/index.ph...roducts_id=279
b.) Normal appearance on others:
https://harmonicdampers.com/index.ph...products_id=62

E-Z pages and other content-only pages appear normally

Not sure what changed to make this happen. I swapped-in an archived template directory, thinking it was a template or css file that got goofed, but no change, so I think it may be a setting in the admin, or a database problem, but I cannot determine what it is.

ZC version 1.5.5e
PHP version 7.4.33

FYI, the sister site to this one is fine: https://honingplates.com/

Thank you in advance for any insight!

The symptoms you're describing are partial whitepages. That implies that the template portion of the page's output started but hit a PHP error and stopped.

Check the site's /logs directory for files named myDEBUG*.log; they'll identify what went wrong and in what file.

Thanks for the reply lat9,

File size of the myDEBUG took a big jump on 13-Jun-2023 03:26:50 UTC

Never done this before. Is it the PHP Warning: callouts that I am looking for?

[lat9]

It's the PHP Errors logged that will be the source of the partial white-screen, but normally the PHP Warnings are harbingers of doom!

I wanted to include in my original post, but forgot, that if I switch to a different template in the admin, everything appears as expected.

The site is running on Westminster New.

That's not a big surprise to me. Check to see that your webhost didn't "help you" by upgrading the site's PHP version (Tools :: Server/Version Info in the admin). Zen Cart 1.5.5 (and especially templates of that era) will choke on PHP versions higher than 5.6 without a lot of care & feeding.

lat9, this actually ties-in to the UPS XML issue we are currently dealing with...

Just found out my hosting company accidentally updated the php version for this domain to 7.4. I just called to check and they set it back within the range for ZC 1.5.5. All pages are displaying fine now.

I have a sub-domain going on this server, where I am building a ZC 1.5.7 site, so I can run the UPS XML plugin. Both domains were accidentally set to php 7.4.

Thank you for your time and that is the story. And thank you also your efforts with the UPS XML plugin!
