Missing Upload button

Check for Javascript errors

If the browser has Javascript features, Fox Contact will build the upload button using Javascript.
The scripts in a web page are executed in sequence, one at a time.
When a javascript exits as a result of an unexpected error, it can stop the execution of all subsequent javascripts.
Hence a Javascript error, even caused by a different script, may stop the execution of Fox Contact Javascripts.

Use the console or development tools of your browser to detect Javascript errors.

Before asking support about an upload button which doesn't show, ensure to fix all Javascript errors on your page.

Check for multiple inclusions of Javascript framework

Joomla includes a Javascript framework by default. It is mootools until Joomla 2.5, or jQuery on Joomla 3 and newer.
Sometimes 3rd party extensions or templates add their own version of the Javascript framework, which occasionally conflicts with the version bundled with Joomla.
Ensure that the html source of your page doesn't load multiple versions of the Javascript framework.
