I was on wp 3.4.1 and all was fine.
Upgraded to wp 3.4.2 and now several plugins are not seeing their private style.css files including this and 'Really simple Facebook Twitter share buttons'.
If I copy all of the contents of the css file that is in the plugin folder and add it to my site css file then all is OK.
My slide titles are displaying beneath the slider - they should be hidden with display: none
My site is still on my local server so I can't send you a link. I have rolled back to wp 3.4.1, thank heavens for Backup Buddy ;-)
I will also post the same message on the 'Really simple Facebook Twitter share buttons' Support page.
