I solved the problem:
To correct this problem, in the CSS file add: padding-bottom: 5px; below padding-left 22px; for warning, message and tips. As follows:
/* Tips, Error, Message, Hightlight*/
.error {
padding-left: 22px;
padding-bottom: 5px;
color: #CC0000;
background: url(../images/bullet-error.gif) no-repeat top left;
}
.message {
padding-left: 22px;
padding-bottom: 5px;
color: #3F89C3;
background: url(../images/bullet-info.gif) no-repeat top left;
}
.tips {
padding-left: 22px;
padding-bottom: 5px;
color: #D79546;
background: url(../images/bullet-tips.gif) no-repeat top left;
}
.highlight {
border-bottom: 1px dotted;
background: #F2F2F2;
font-weight: bold;
}
