This plugin is designed to be placed at the top of the page of your site, in a position using the shortcode {jomres bs5_top_panel} or [jomres bs5_top_panel]
It produces a set of buttons as shown below. The Currency and Language buttons produce modal popups that the guest can use to select their currency and the currently active language. The List your property, Register and Sign in buttons are active/inactive depending on whether the guest is logged in or not.
You will need to install the appropriate languages that you want to use in the CMS yourself, Jomres doesn't install the host CMS's languages. You can choose which languages are shown in Site Configuration > Choose languages tab.
You must remember to save an Open Exchange Rates API key in Site Configuration > Integrations and ALSO enable the "Use conversion functionality" setting in Site Config > Currency Conversion/Currency codes tab.
