It is a new installation, I use Google Chrome, I disabled the add blocker and it is the sam thing, also I tried with Edge and Firefox, it is the same thing.
Thanks for confirming that and testing it out on other browsers too.
Can you make sure you aren’t dragging the first buttons (the preview ones) shown on the screenshot – with the red arrow – but rather the ones below –inside the green box?
If this still happens, do you mind contacting us via email by clicking on our green Support button at the bottom right of sharethis.com/support and sending us a screen recording (.mp4, .mov) of the issue?
Thanks for these insights, it seems the theme you are using is causing these conflicts with the plugin. We followed back the conversation on the email you sent us!
