It looks like you have enabled a WD setting that puts out clientraw-type metadata in all processed files.
Go to Weather-Display, Setup, Advanced/Misc Settings, Program TAB
In the General group, UNTICK 'Raw data appears in your HTML webpage for others'
That should remove the raw data clientraw.txt from your webpage (and all the .php uploads like testtags.php).
If that doesn't work, then restart WD .. it's gotten confused and is adding clientraw.txt raw data to your webpages.
