PHP warnings suddenly start appearing in the log folder

[delia]

It seems to be mostly commented out. It is the default file for 1.5.1

  $list_box_contents[$rows][$col] = array('align' => $lc_align,
                                              'params' => 'class="productListing-data"',
                                              'text'  => $lc_text);
    }

    // add description and match alternating colors
    //if (PRODUCT_LIST_DESCRIPTION > 0) {
    //  $rows++;
    //  if ($extra_row == 1) {
    //    $list_box_description = "productListing-data-description-even";
    //    $extra_row=0;
    //  } else {
    //    $list_box_description = "productListing-data-description-odd";
    //    $extra_row=1;
    //  }
    //  $list_box_contents[$rows][] = array('params' => 'class="' . $list_box_description . '" colspan="' . $zc_col_count_description . '"',
    //  'text' => zen_trunc_string(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))), PRODUCT_LIST_DESCRIPTION));
    //}
    $listing->MoveNext();
  }

No, it's totally commented-out! Do you have anything in /includes/modules/classic/product_listing.php?

You're looking at the wrong thing then Delia. Line 178 was the caller of the function that gave the warning - it can't be commented out. Check the template value again in admin->tools->Template Selection.

New information does make it look like there are server changes. So I'm going to leave it at that.

The cart had changes to the default 1.5.1 version and all of those changes no longer work. Perhaps changed for an earlier version of PHP? I don't know but there are definitely more issues than the simple changes I made.

Thanks everyone for providing assistance and advice. You are the reason why I am a Zen Cart person!!!!!

I just checked several other 1.5.1 sites on the server and they are not throwing errors. That should help with the troubleshooting a bit

There had been changes to some of the default files on the server and it does look like they might have been the source of the problems. Turns out there was actually a full php error happening in checkout. The client finally realized she hadn't gotten an order all day. Once she checked it out and ran into that white screen of death, I was able to pinpoint the file and the problem for that. Something had been commented out that all of sudden needed to be used. I'm sure we'll never really know all the details and I figure all her problems will be resolved once she upgrades to 1.5.4.

That's the dangers of coming into an existing website... Troubleshooting becomes a major part of my job and some days, I just don't want it to be!

Once again thanks everyone.

So I'm told that the reason was discovered " turns out it was an invalid admin settings for the product listing description. the value was blank and it should have been 0." Never occurred to me that could be a problem. Next time weirdness arises perhaps I should look deeper into the database!
