Upgrade to php 5.4 Causes Error

I use 1&1 to host my website. It is asking me to upgrade from php 5.2 to 5.4.

First I updated wordpress to 3.5.1, and updated all my plugins. Then I switched to 5.4.

Now I have this error at the top of my site:

Warning: Illegal string offset ‘name’ in /homepages/38/d288486085/htdocs/home2/wp-content/plugins/genesis-simple-sidebars/plugin.php on line 106

Warning: Illegal string offset ‘description’ in /homepages/38/d288486085/htdocs/home2/wp-content/plugins/genesis-simple-sidebars/plugin.php on line 108

Line 106 is ‘name’ => esc_html( $info[‘name’] ),

Line 108 is ‘description’ => esc_html( $info[‘description’] ),

I’m not a programmer, so I don’t know what to change without potentially making it much worse.

Thanks!
