Doesnt work on newest version

Thanks for the plugin. I have the same question about compatibility on latest WP version.

An error occurs on WP4.8:

Warning: simplexml_load_string(): Entity: line 1: parser error : Start tag expected, ‘<‘ not found in /www/doc/www.knihovnapocernice.cz/www/wp-content/plugins/soslider-social-slider/handlers/facebook/init.php on line 262

I was facing one more issue in enqueuing css in admin panel

replaced this:
$contentCss = implode( “, “, $contentCssArray );

to this:
$contentCss = “, “.implode( “, “, $contentCssArray );
