And it does not fix the background of the register button at the top and the background at about conference module, nore the background of the button in the slideshow.
The css add is a nice patch for the countdown , but not really tackle the whole issue.
Why does it desappear in the first place ?
It works again when i upload the original t4 css in the media directory. As soon as i change an option, this css is replaced and it s all gone
so something goes wrong with t4 when i change the css options in the template
