site (in development) : http://www.wp.storyofusfilms.com/blog/
Only first blog post does not have the share buttons. I'm using the "custom code" option.
Before using custom code, just the first blog post here was getting incorrect share buttons (email and "more" replaced two others). I know there is one JS error and I have removed the code causing the error and it made no difference to problem with addthis.
Thanks for any help.
