To bring your share buttons back no matter what your custom html settings are follow these instructions:
1: From your Blog, click on the link named "Design" at the top right of your page.
2: Click on "Edit HTML"
3: Check the box called "Expand Widget Templates"
4: Click in the box and press ctrl+f or use your browser's search function.
5: Search for "shareButtons"
6: Below this you will see three lines spaced about 5 lines apart each that read like this:
< a class = 'shared-button sb-email
< a class = 'shared-button sb-blog< a class = 'shared-button sb-buzz
< a class = 'shared-button sb-twitter< a class = 'shared-button sb-facebook
After each of the first ' characters paste this code:goog-inline-block
So that each line reads like this:
< a class = 'goog-inline-block shared-button sb-email...
< a class = 'goog-inline-block shared-button sb-blog..
etc.This should fix everything. Remember to click on "Save Template" when you are done. :)
Hopefully, this tips / tricks will help all of the IT novice out there..=)
P/S : Frankly, I write this tutorial mainly for myself so that I don't need to do the searching all over again when I want to change my templates again =P
