Warning: Illegal string offset 'script'

Hello,

I changed hosting for my site and it seems that your plugin crashed. What it does is that on pages that list articles and also on article page I get this message:
“Warning: Illegal string offset ‘script’ in /home/machomen/public_html/wp-content/plugins/wp-socializer/includes/wpsr-shortcodes.php on line 52”
The buttons are working properly, it’s just that this warning shouldn’t appear. I tried deleting the plugin and reinstalling it, but no change.

Could you point me in the right direction for fixing this? Strange enough, but line 52 in the specified file is completely empty.

Thank you!
