I have found a fix. I’m useless with code and am very much a trial an error kind of guy so I’m pretty pleased!
Take a look at one of my pages: https://drumtrip.co.uk/news/what-is-jungle-the-history-1992-to-1996/
First of all, visit the Share button page at Facebook Dev: https://developers.facebook.com/docs/plugins/share-button
Create your button, but if you are using this on multiple blog pages be sure to leave the URL field blank. You can define a permanent URL here if you wish (for a static homepage for example) but in the instance of your blog, you leave it blank and code will share whatever URL it is on.
Click the “Get code” button.
Add the first lot of code (JavaScript SDK) in your themes <head> tag.
Now find the second lot of code (for plugin). Open up Flare settings in wordpress admin and go into the ‘share’ settings. On the Facebook share button settings click the “or paste in code snippet” button.
In here add the second lot of code for the sharing button.
Hit save.
Thats it.
As you can see on my blog example, I have used the single button share for the horizontal bar and the box counter button share for the vertical bar.
Just make sure you re-do this process if you upgrade the plugin!
