Additional comments

I've created the custom module manually by following the official Joomla documentation. The module is designed to display a simple text block. I've tried placing the module in various positions within my template, but it consistently fails to appear.

I've also attempted to create a basic HTML module with the same name to see if the issue was specific to my custom module, but the result was the same.

I've checked the Joomla error log, but there are no relevant error messages.

Relevant code snippet from my module's XML file:

XML
<extension version="3.1" type="module" client="site">
    <name>mod_mymodule</name>
    </extension>
