Php Warnings And Notices Fn.common.php

Running CS-Cart 4.15.1 with PHP 7.4 with OPCache and ACPu. LAMP server.

Just upgraded from 4.11.3 and looking at the PHP log.

I get this Warning a lot:

PHP Warning: Invalid argument supplied for foreach() in /public_html/app/functions/fn.common.php on line 8669

I get this Notice a lot:

PHP Notice: Trying to access array offset on value of type bool in /public_html/app/functions/fn.common.php on line 1956

Line 8669 is in this function:

function fn_sort_by_ids($items, $ids, $field = 'product_id')
    $tmp = array();
foreach ($items as $k => $item) {
    foreach ($ids as $key => $item_id) {
        if ($item_id == $item[$field]) {
            $tmp[$key] = $item;


return $tmp;


Line 1956 is in this function:

function fn_get_session_data($var = '')
    /** @var \Tygh\Web\Session $session */
    $session = Tygh::$app['session'];
if (!$var) {
    $return = [];

    foreach ($session['settings'] as $name => $setting) {
        if (empty($setting['expiry']) || $setting['expiry'] > TIME) {
            $return[$name] = $setting['value'];
        } else {

For the life of me, I can't figure out what's wrong with either the data, or maybe it's a misconfigured block. It's driving me nuts. I optimized the database.

Any ideas? How do I debug this?
