Missing Media Files - akeeba/onthos GitHub Wiki

The extension lists some files that need to be placed under its media folder subdirectory, but some or all of these files are missing.

Why is it a problem?

The extension's media subdirectory usually contains the extension's CSS stylesheets and JavaScript files. Without these files the extension will not display correctly in a browser, nor will it function properly – or at all.

Suggested fix

You will need to reinstall the extension to make sure the missing files are installed back into your site.

It is recommended that you install the package which contains the extension twice in a row, without uninstalling it before or in between.
