Hello,  
I finally figured out how to import an existing WP site into Local by FlyWheel. I uploaded a zip file containing the site .sql database and the /wpcontent directory. During the configuration I chose the “Preferred Configuration” option. The site loaded successfully. I was able to navigate the pages of the site powered by Local by FlyWheel without any troubles.  
However, each time I clicked on the “Admin” button to access the site WP Control Panel, I received this error message which apparently has something to do with the Revolution Slider plugin:  
“Fatal error: Uncaught Error: [] operator not supported for strings in /app/public/wp-content/plugins/revslider/includes/framework/base-admin.class.php:69 Stack trace: #0 /app/public/wp-content/plugins/revslider/admin/revslider-admin.class.php(410): RevSliderBaseAdmin::addMetaBox(‘Revolution Slid…’, ‘’, Array, NULL) #1 /app/public/wp-content/plugins/revslider/admin/revslider-admin.class.php(69): RevSliderAdmin-\>addSliderMetaBox() #2 /app/public/wp-content/plugins/revslider/admin/revslider-admin.class.php(46): RevSliderAdmin-\>init() #3 /app/public/wp-content/plugins/revslider/revslider.php(150): RevSliderAdmin-\>\_\_construct(’/app/public/wp-…’) #4 /app/public/wp-settings.php(305): include\_once(’/app/public/wp-…’) #5 /app/public/wp-config.php(107): require\_once(’/app/public/wp-…’) #6 /app/public/wp-load.php(37): require\_once(’/app/public/wp-…’) #7 /app/public/wp-admin/admin.php(31): require\_once(’/app/public/wp-…’) #8 /app/public/wp-admin/index.php(10): require\_once(’/app/public/wp-…’) #9 {main} thrown in /app/public/wp-content/plugins/revslider/includes/framework/base-admin.class.php on line 69”

Thank you for the help
