atec Translation Status is a diagnostic and maintenance plugin that helps you understand the real state of translations in WordPress.
Modern WordPress automatically compiles translation files for performance. When translations are missing, outdated, or incorrectly loaded, WordPress usually fails silently — no warnings, no errors. 
This plugin makes translation issues visible and actionable.
What it does
<ul>
<li>Lists all active (loaded) textdomains</li>
<li>Detects whether translation files (.mo) exist</li>
<li>Detects whether compiled translation files (.l10n.php) exist (WP 6.5+)</li>
<li>Checks whether compiled files are out of date</li>
<li>Clearly indicates when:
<ul>
<li>translations are missing</li>
<li>compiled files need rebuilding</li>
<li>plugins or themes do not follow WordPress translation conventions</li>
</ul>
</li>
</ul>
What it does not do
<ul>
<li>It does not replace WordPress’ translation system</li>
<li>It does not generate translations</li>
<li>It does not modify plugin or theme code</li>
</ul>
Instead, it helps you identify problems, rebuild safely, or contact the responsible plugin/theme developer with clear evidence.
<h3>Third-Party Services</h3>
<h3>Integrity check</h3>
