Today I installed jLexBlock on a website running on php7
When calling the component I get following warnings:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Services_JSON has a deprecated constructor in myroot/public_html/cn_circusnews.v4/administrator/components/com_jlexblock/helpers/class.json.php on line 126

What do I have to do?
