Red Agency Theme

Thanks a lot for your help.

You can change Nanoslider JQuery version with newest (for example with 1.11.3). And check the functioning of the plugin.
You can copy this version of JQuery from RA theme to plugin folder: /plugins/nanoslider/js/
Then open nanoslider.php file and change parameter:
/plugins/nanoslider/js/jquery-1.8.2.min
to /plugins/nanoslider/js/jquery-1.11.3.min
on line 248.
Then uncheck JQuery loading from RA theme.

In addition to what you wrote above, I needed to change the jqeury version in /admin/inc/plugin_functions.php:
$jquery_ver    = '1.7.1';
to $jquery_ver    = '1.113';
on line 32.

After that, both dropdown menu and nanoslider plugin are working!
