Gravity forms required field error, blank data

Hi All,

Been having trouble with gforms on one site. Text input fields were giving a required error even though they were filled, so i just took the required off those fields but now the form isnt recording the data at all from those text fields… i have dropdown fields and those are fine, no errors.

I have updated all plugins, deactivated all plugins except gforms, updated wordpress, tried the site on a different server, almost everything. am so stumped and stressed about it

Any help greatly appreciated.
