     <h2>File Permissions  &#38; Size Checker</h2>
     <h4>To read more about permissions check out
     <a href="http://codex.wordpress.org/Changing_File_Permissions">http://codex.wordpress.org/Changing_File_Permissions</a>
     <br>Files set to .777 will have a red mark <span class='red'> &#215; </span> as they can compromise your security, especially for directories.
     </h4>
     <p></p>
     <p><b>General rule of thumb:</b>| &#8226; Folders set to  755 or 750 | &#8226; Files set to 644 or 640 | &#8226; Important files (wp-config.php) should have more strict permissions like 600<p>
