• On trying to activate this plugin, it produces a fatal error:
    Fatal error: Cannot redeclare custom_upload_mimes()

    After deactivating the plugin that has already declared custom_upload_mimes(), and then trying again, I get:
    Fatal error: Cannot redeclare register_mysettings()

    Thankfully, if I deactivate the plugin that has already declared register_mysettings(), this plugin activates successfully.

    Please could you add some code to check whether these two declarations have already been made?
