Read this post. Maybe that will answer your questions. It did for me!

It was not the case.

But I found who “was guilty”- W3 Total Cache

 After I disabled the plugin it started to work… In my opinion it is a bug…

1) I know what is wrong.

While being logged and putting buttons in order you want to have on your forum you HAVE TO make CTRL+F5 – you will see after that then … buttons you have chosen has …. changed .

After making the same a few time you will be able to chose and to put the chosen buttons in your wished order.

2) I have second suggestion – it would be great to have all butoon in one size

a bug in w3tc?  you will have to take it up with them…  as to the forum, just tell w3tc not to cache the forum page for ALL types of caching in place… each forum page is dynamic so caching is wrong…

as to the icons, you need to take that up with google plus and facebook…    nothing Share This or us can do about it…  Those are native application icons and the api gives you no options to style or change…

sounds like your browser is aggressively caching if you have to reload that many times…  

Thanks for your prompt answer – after writing prevous post I started to wonder if it is not upt o Google and Facebook. I see I was right

I appreciate the Forum – looks amazing and is nice in working. Thanks for 4 new plugins as well

no worries… thanks for kind words… many, many folks have asked google and facebook to make their two buttons consistent or at least an api so they can be modified.. understand why they want it to look the same everywhere too…
