 * Hi,
   First of all, awesome plugin, use it every day in my workjob 🙂An annoying
   issue i’ve found is that QM is spamming my **debug.log** with this when i go 
   to the frontend:
 *     ```wp-block-code
       [31-Aug-2024 00:51:38 UTC] PHP Warning:  Undefined array key "C:/laragon_new/www/XXX/wp-content/themes/XXX/parts/header.html" in C:\laragon_new\www\XXX\wp-content\plugins\query-monitor\output\html\theme.php on line 163[31-Aug-2024 00:51:38 UTC] PHP Warning:  Undefined array key "C:/laragon_new/www/XXX/wp-content/themes/XXX/parts/footer.html" in C:\laragon_new\www\XXX\wp-content\plugins\query-monitor\output\html\theme.php on line 163
       ```
   
 * 
   For info, **i use PHP 8.3** at the moment but i don’t think _(not quite sure)_
   that’s it’s related.What i found out is that QM seems to be collecting data differently
   about “paths” on Windows (which is causing the PHP Warnings.When i log **$parts**
   and **$data->count_template_parts**, i can clearly see that **one is using forward
   slashes** but the **other one** **is using a mix**, the logs:
 *     ```wp-block-code
       [31-Aug-2024 00:59:27 UTC] DEBUG: $parts Array([C:/laragon_new/www/XXX/wp-content/themes/XXX/parts/header.html] => parts/header.html[C:/laragon_new/www/XXX/wp-content/themes/XXX/parts/footer.html] => parts/footer.html)[31-Aug-2024 00:59:27 UTC] DEBUG: $data->count_template_parts Array([C:\laragon_new\www\XXX/wp-content/themes/XXX/parts/header.html] => 1[C:\laragon_new\www\XXX/wp-content/themes/XXX/parts/footer.html] => 1)
       ```
   
 * 
   If you have an idea on how to fix this, that would be great 🙂Have a good day,
   Damien
