 * That’s the warning on admin panel:
 * `Warning: call_user_func_array() expects parameter 1 to be a valid callback, 
   class 'Wslm_BasicPluginLicensingUI' does not have a method 'printPluginRowNotice'
   in D:\web\htdocs\wp\wp-includes\plugin.php on line 429`
 * Any fixes? Ty!

 * Hmm, that’s unusual. Which plugin version do you have installed, and is it the
   free or Pro edition?
 * Overall, it sounds like there might have been some kind of a problem with the
   installation process. Try re-downloading and reinstalling the plugin.
