Ok I got google + 1 to work by going to addthis plugin settings and using my own custom button using this code
<a class="addthis_button_google_plusone" g:plusone:size="large" g:plusone:count="true"></a>
However when i use this custom button, i cannot use the other service buttons such as
Facebook, Twitter, Google, Print
Any ideas how do i add size 32x32 of those icons and also keep google plus + as well ?
For now i am using the google + 1 as that would help my search engine rankings, but it's a shame i can't provide the other service buttons and more for people to share my links :[
