Hey vald84,
Thanks for the URL. I looked at that page and their appears to be a javascript error that’s affecting page functionality, including Shared Counts.
Hard to tell what the exact cause is, but one thing I noticed that’s is not correct is the site is loading the jQuery javascript library from your theme, instead of the copy that is included with WordPress, which is what’s expected.
For context, your theme is loading jQuery version 1.6.1 which was released in May 2011. The current version that WordPress includes (and what plugins expect to find) is version 1.12.4 which was released in May 2016.
So the first thing I would recommend would be to use the version of jQuery that WordPress includes, instead of loading your own out dated version that’s included in the theme.
I don’t think this is related, but it’s worth nothing there are also PHP errors on the site as well, see https://cl.ly/cc28f26621fa
Hope that helps!
