Invalid Argument Warning in feedwordpress.php:2126 (v2024.1119)

[fl0om]

PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/feedwordpress/feedwordpress.php on line 2126

This warning repeats multiple times in the logs, suggesting that the same issue is occurring repeatedly during execution.

It appears that an invalid argument (likely null or another non-iterable type) is being passed to a foreach loop on line 2126 of feedwordpress.php. foreach expects an array or an object that implements Traversable.

Suggestion:

It would be helpful if the plugin could include a check before using foreach, such as:

if (is_array($var) || is_object($var)) {
    foreach ($var as $item) {
        // ...
    }
}

This would prevent the warning from appearing and help ensure smoother execution.

Current system configuration:

• WordPress version: 6.8.1
• PHP version: 7.3.31
• Web server: nginx/1.14.2
• Database: MariaDB 10.3.39

I recognize that my environment is slightly outdated, and I plan to update PHP and other components soon. However, I wanted to report this issue in case the plugin could benefit from an additional safeguard.

I noticed that the warning stopped appearing when I disabled the FeedWordPress Diagnostic feature. This might indicate that the issue is related specifically to the diagnostic logging process rather than the core functionality of the plugin.
