    help question PHP Problems after Upgrading (production sys) but also on Fresh install (test sys)

    I just upgraded to the newest version 1.5.7f.
    I'm using the German version (zen-cart-pro.at).

    1. Various items e.g. "stats_products_lowstock" in the admin don't work and show up a simple white HTML error page and an additional warning log (see below):

    HTML Code:
    [11-Apr-2023 09:02:32 Europe/Berlin] PHP Fatal error: Uncaught Error: Call to undefined function error_log() in /includes/extra_configures/enable_error_logging.php:91

thrown in /includes/extra_configures/enable_error_logging.php on line 91
    2. On a test subdomain I installed a fresh installation which also shows the following error:

    1. Installation with 8.0.27 finishes well
    2. Loading Frontend and Backend shows only white page / HTML error
    3. Switching to PHP 7.4.33 and reloading works
    4. Switching then back again to 8.0.27 and reloading also works !!! for Frontend and Backend, but with the above problems and error logs.


    The maintainer of the German version says I haven't uploaded all files. But I compared the downloaded file and I unzipped the full file directly on the server via SSH.

    3. Another curiosity is that the module for showing "price per unit" disappears in the Fronend when switching to PHP 7.4.33

    Any help is very appreciated.

    Information about my system

    zc German version (zen-cart-pro.at) 1.5.7f
    debian stable

    I tested another hosting which runs Ubuntu and PHP 8.0.28.
    There don't appear these kind of problems.
    Though there are warning logs too (but different kind of)

    Code:

    no chance to have running it with PHP 8.0
    Create Account resulted in an Error Page

    So switched down to 7.4.33 meanwhile.

    Here another error message at admin -> database-backup (translated)

    Code:
    ERROR: This Backup-Skript seldom works, if safe_mode is activated or if there are open_basedir restrictions.
    Code:
    MySQL Tools (mysql, mysqldump) not found.

    Are there any error logs in the /logs folder?

    Open the log file that is generated by "but then HTML error with PHP 8.0" and post its contents here.

    Go to your admin's Tools :: Server/Version Info and find occurrences of error_log on the screen. It 'looks like' your webhost (for whatever reason) has added the base PHP error_log function to your site's disabled_functions list.

    You'll need to contact your webhost to get that corrected.
