Parse error and syntax error

Hi there,

I wouldn’t call myself a novice, however I am reasonably new to using WP and building my website predominently by myself, with some assistance from my far more experienced brother. He is unavailable to help at the moment so I’m turning to the good folk here for help.

My website is almost ready to go live and in an attempt to add the social icons code via Symple-Shortcodes I now receive the following error at every menu or dashboard link:

Parse error: syntax error, unexpected ‘.’ in /home/homele14/public_html/wordpress/wp-content/plugins/symple-shortcodes/symple-shortcodes.php on line 29

I have my FTP File Manager open and have been able to locate the .php location of the file where the error seemingly appears. Here is the first 70 lines of code using Notepad++, which includes the Symple-Shortcodes-social-icon area:

<?php

/* Clear Floats
================================================== */
.symple-clear-floats {
clear: both;
}

.symple-clearfix:after {
content: “.”;
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}

/* Spacing
================================================== */
.symple-spacing {
display: block;
height: auto;
margin: 0 !important;
padding: 0 !important;
background: none !important;
border: none !important;
outline: none !important;
}

/* Social
================================================== */
.symple-social-icon{
display: inline-block;
margin-right: 5px;
}
.symple-social-icon img{
display: inline;
border: none;
outline: none;
padding: 0;
margin: 0;
box-shadow: none !important;
}
.symple-social-icon img:hover{
opacity: 0.8;
}

According to Notepad++, line 29 is this one:
.symple-clear-floats {

Can anyone help me restore it all back to a functioning site (I don’t care if for the moment I don’t have the social-icons present) or provide a working solution to include the social-icons?

Your help and advice is greatly appreciated.
