Three errors floods my log! HELP!!!

Just got my website going a week ago and today I noticed that the error log fills up really fast by the same errors (see below). The row numbers for the first error are 178, 179, 180 and 183:

8: Undefined variable: smflang
File: D:\www\danceaddict\modules\mod_jflanguageselection.php
Row: 183

This second error has the row numbers from 199 to 225:

8: Constant _UE_ already defined
File: D:\www\mysite\components\com_comprofiler\plugin\language\swedish\swedish.php
Row: 225

The third and last error is:

8: Constant _ISO already defined
File: D:\www\mysite\components\com_comprofiler\plugin\language\swedish\swedish.php
Row: 17

I've looked at the files and rows but there is nothing there to edit? Everything looks good and the same errors with all installed languages (swe, eng, nor, fin). If I clean the log out of errors and then refresh the page I get three pages filled with these errors right away and if refresh again there comes three more pages and so on, so these three errors floods the error log!

Please help me, really need to get rid of these errors! Cry
