The AddThis icons only appear in Chrome - not in Firefox, IE 10 or Safari. I get the following error message when deactivating the plugin:
Warning: Call_user_func_array() [function-call-user-func-array]: First argument is expected to be valid callback, 'smart_layer_save_settings' was given in /home2/maddy/public_html/utahoutsider.com/wp-includes/plugin.php on line 199.
I'm using The Cotton theme by Pexeto. site URL is utahoutsider.com
Any idea how to get the plugin to work in all browsers?
