Thanks for your response.
In your FAQ you write this:
If your theme files or another plugin are not using the WordPress standard method for loading the jQuery library this may result in jQuery being loaded a 2nd time, causing the plugin files to be overwritten.
Check the page source code to see if there is a second instance of jQuery and if so, remove the code from your theme files.
That’s obviously not very helpful as you can sort of assume that there will be other jQuery instances running on most modern websites.
You as the developer of this plugin should make it so that if jQuery already has been loaded, it doesn’t load for a second time. If it is not loaded you can load it. Hence my comment and rating. If you fix it, the rating goes up, very simple principle really.
And as a matter of fact, your FAQ section is not really helpful at all…
Regarding the tweet button not showing, screenshot of your site: https://senl.in/nfZ81U
Other plugins show it perfectly fine.
