I applied the htaccess rules as stated in the readme.
Code:
RewriteRule ^/?(af|sq|ar|be|bg|ca|zh-CN|hr|cs|da|nl|en|et|tl|fi|fr|gl|de|el|iw|hi|hu|is|id|ga|it|ja|ko|lv|lt|mk|ms|mt|no|fa|pl|pt|ro|ru|sr|sk|sl|es|sw|sv|zh-TW|th|tr|uk|vi|cy|yi)/$ index.php?language=$1&vbet_outside=true [L,QSA]
RewriteRule ^/?(af|sq|ar|be|bg|ca|zh-CN|hr|cs|da|nl|en|et|tl|fi|fr|gl|de|el|iw|hi|hu|is|id|ga|it|ja|ko|lv|lt|mk|ms|mt|no|fa|pl|pt|ro|ru|sr|sk|sl|es|sw|sv|zh-TW|th|tr|uk|vi|cy|yi)/(.*)?$ $2?language=$1&vbet_outside=true [L,QSA]
RewriteCond %{QUERY_STRING} !vbet_outside=true
RewriteRule ^(.*)$ $1?vbet_outside=true [L,QSA]
While Page Not Found - PentaxForums.com did not return a 404, the page was not translated (obviously, since there's no vbet init there), and, furthermore, all links from that page returned the 404 as vBSEO CRR's stopped working.
Therefore, let's just take the simpler solution and save ourselves a headache:
How to I prevent forum links from translating?
Currently, Pentax Lens Review and Specification Database - Main Index (a link) is rewritten to http://www.pentaxforums.com/forums/pl/lensreviews/ (404).
I want the link to remain unchanged.
