implemented canonical url-s, got some weird ...

[goxy63]

yesterday I did that as per this thread here:
https://vborg.vbsupport.ru/showthread.php?t=253656
My settings are:


Also in two of my .htacces files [one under public_html, and another one under public_html/forums] I placed mentioned code from thread above:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

Lost about 50% average visitors per day, and got me some weird thing in who is online area, guests are visiting some uknown locations, please check pictures bellow




those locations are weird, when I click on link in who is online I got error message
"Invalid Forum specified. If you followed a valid link, please notify the administrator"

some of those locations are quite strange [for me] as they dont lead anywhere but guests [robots and real people] are trying to see those "unknown locations"

some of them are:
Unknown Location

Unknown Location
/forums/showthread.php/3253-Erotske-price-Stare/images/misc/im_msn.gif

My question is what are those links, and will this and how much affect my small site regarding to visitors, google ?

In adminCP shoould I maybe choose "mod rewrite friendly urls" from present "advanced friendly urls"[think not]...forgot to mention that before I was using "basic" friendly urls and I never touched this option...

Thanks for any advice or opinion

cheers
