This hack is in response to a user who wished to not show the validation error messages that appear after fields on the forms. The easiest way to remove the messages would be to hide them with CSS (rather than disabling them in PHP code).
Open screen.css
Find the selector for p.css and change it to say:
p.err {
/*
margin: 3px 0 0 0;
padding: 0;
background: url(sc_admin/res/error_arrow.gif) no-repeat;
font-size: 1.1em;
font-style: italic;
text-indent: 20px;
color: #cd0000;
*/
display: none;
visibility: hidden;
}
This comments out the original styling and makes the paragraph disappear.
Alternatively, if you want to remove the red borders on single line fields and textareas, find the line in the CSS that says:
div.obj input.err, textarea.err {border-color:#cd0000;}
Change it to say:
div.obj input.err, textarea.err { /* border-color:#cd0000; */ }
This will remove the red borders.
I recommend disabling rather than deleting code in these cases, in case you change your mind later.
