If you need support from Yola please contact us via email@example.com or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
The easiest way would be to put your Form Widget on top of a Custom Panel Widget for which you choose a suitable background colour. This should make the font visible. If that doesn't work, please let me know, and I'll work out a coding solution for you.
