Have you ever seen an error log like the one below?
<blockquote>
PHP Fatal error: Allowed memory size of xxxxxx bytes exhausted (tried to allocate xxx bytes) in /var/www/wordpress/wp-includes/wp-db.php on line 2007
</blockquote>
This means that <a href="https://www.php.net/manual/en/ini.core.php#ini.memory-limit" rel="nofollow ugc">PHP memory limit</a> is exhausted while retrieving data from a database. In any case, this happens when your site has big data and makes insane loops inside.
But we want to know that which plugin tried to retrieve data?
Hagakure adds extra information to error.log file when <code>wp-db.php</code> causes memory limit error:

This log will always follow the memory limit Fatal Error by <code>wp-db.php</code>. Now you can find <code>#8</code> calls <code>get_posts</code> repeatedly.
We recommend watching logs with notification services like <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html" rel="nofollow ugc">CloudWatch Logs</a>. 
This error occurs in the productional environment, and you may not have a chance to see it occurs. 
We use Hagakure with our <a href="https://hosting.kunoichiwp.com/" rel="nofollow ugc">hosting service</a>, please look forward to seeing <a href="https://kunoichiwp.com/blog" rel="nofollow ugc">our blog published</a> and describing the integration!
This plugin also adds debug backtrace to error logs. To modify the error level to a detailed backtrace, define the constant in <code>wp-config.php</code> or somewhere else:
<pre>define( 'HAGAKURE_ERROR_LEVEL', E_NOTICE | E_USER_WARNING | E_WARNING | E_USER_ERROR );</pre>
Besides that, if <code>SAVEQUERIES</code> is set <code>true</code>, the slow query log will be logged with PHP debug backtrace. This helps you to debug.

Have images on your server but they don’t appear in your Media Library?
<a href="https://mediarecoveryplugin.com/?utm_source=mlr&utm_medium=free_plugin&utm_campaign=readme_md" rel="nofollow ugc">Media Library Recovery</a> helps you recover lost media files in these common scenarios:
<ul>
<li>After site migration – Moved from localhost to production and media is missing</li>
<li>After hosting transfer – Changed hosts and files didn’t sync properly</li>
<li>After database restore – Restored from backup but lost media library entries</li>
<li>Orphaned files – Files exist in <code>wp-content/uploads</code> but don’t show in WordPress</li>
<li>Development/staging sync – Pulled production DB to staging and lost media</li>
<li>Broken image links – Images show on server but broken in posts/pages</li>
</ul>
The plugin scans your uploads folder, finds orphaned media files, and rebuilds the WordPress database entries to restore them to your Media Library.

Media Library Recovery – Restore Lost Image Files

It was great to have my images back showing into the WordPress media library.

Great, plugin. Keep up the good work/

Nice one, recovered my unlisted images

Limits you to recovering 10 files at a time. User interface is very confusing. In addition, as shown below, the developer is sarcastic and blames users for the developer's failure to do any usability testing.

Nearly useless

Recover missing media files after site migrations, hosting transfers, database restores, or when files exist on your server but are missing from your  …
