installation

hello there,
I installed the latest version of the plugin but can’t find it in the dashboard!

and I’m seeing this msg: Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘NimblePortfolioPlugin’ does not have a method ‘adminNoticeAddonUpdate’ in /home/jame7075/public_html/wp-includes/class-wp-hook.php on line 298

I’m not sure if it is related or not

please help

thank you in advance
