500 Error When Saving Elementor Page – Stratum Plugin Warnings on PHP 8.2.28

Hi there,

I’m encountering a 500 Internal Server Error when trying to save a page using Elementor on my site.
```
PHP Warning: Undefined array key 0 in /wp-content/plugins/stratum/includes/templates/table.php on line 85
PHP Warning: Trying to access array offset on value of type null in /wp-content/plugins/stratum/includes/templates/table.php on line 85
(repeats multiple times)
```
The issue appears to stem from a deprecated or improperly handled array access in Stratum’s table.php file. Likely cause: the plugin is not fully compatible with PHP 8.2.28, as null array access behavior is stricter in recent PHP versions.

Steps Tried:
- Deactivated Stratum plugin → issue resolved, page saves normally
- Re-activated → issue returns
Request:

Could the plugin author please:
1. Review compatibility with PHP 8.2.x
2. Add checks before accessing undefined array keys or null values (e.g. isset($array[0]) or !empty($array))
Until then, the only workaround seems to be disabling Stratum, which isn’t ideal for my setup.

Thanks in advance for your support!

P.s. the page https://wordpress.org/plugins/stratum/ says it supports “5.6 or higher” but as we can see so far it’s not completely true.

After further investigating, it seems to related to the newest version of Stratum.

I changed in ngixn the php version to 7. And … the same problem!

[24-May-2025 21:22:24 UTC] PHP Notice:  Trying to access array offset on value of type null in /var/www/example.pl/wp-content/plugins/stratum/includes/templates/table.php on line 90

[24-May-2025 21:22:25 UTC] PHP Notice:  Undefined offset: 0 in /var/www/example.pl/wp-content/plugins/stratum/includes/templates/table.php on line 90

I fixed it this way:

<?php

use \Elementor\Frontend;

extract(shortcode_atts(array(
    'table_head_items' => array(),
    'table_body_items' => array(),

    'table_body_alignment_horizontal' => '',
), $settings));

$class = 'stratum-table';

$table_tr = [];
$table_td = [];

$frontend = new Frontend;

?>

You can compare.

It now works, however something slowed down. All the pages get saved very fast in elementor. but the page with the stratum table takes almost 1 minute. I had to increase the max_execution_time from 30 second to 60 seconds.

The PHP Notices are not appearing anymore.

Can you please apply an official fix?
