Thanks for the reply.
Per your suggestions, I unchecked the “transparent” box for Theme Color.
I also unchecked all boxes for “Transparent” on the General > Coor Settings section.
That said, the text and hyperlink text are still difficult to see on the desktop, laptop, and mobile (Samsung 6 phone). (Desktop and laptop were in both Chrome and Firefox.
Finally, there was another form plug-in that I have deactivated and uninstalled but the form still appears to be having problems – specifically the fields are extending too far to the right.
