Download button hides, cause white on white format after updating

Hi,

some clients called me in the last weeks, that the downloads are broken or disappeared.

After investigating this, we have discovered that the original formatting for the download button is incorrectly replaced by an update. Because now the download buttons are formatted white on white and so they are no longer visible to most people, but they are there!

Could you please fix it asap ??

Thx
Stefano
