Not really sure if I miss something but after hours puzzling I thought to ask you.
My site uses a component that unfortunately creates double content (if you appoint 2categories to items). SEO doesn't like this so a redirect is needed. Basically the following urls display the same info and there are many more of similar form:
https://www.divemood.com/liveaboards/offers/emperor-serenity-s-best-of-maldives-19-february-2017
https://www.divemood.com/liveaboards/emperor-serenity/emperor-serenity-s-best-of-maldives-19-february-2017
So I thought piece of cake and went into your .htaccess maker and added at the end:
RewriteRule ^/offers/emperor-serenity-(.+)$ /emperor-serenity/emperor-serenity-$1 [R=301,L]
To my knowledge should work, but ... no such luck. Could something be blocking this or am I missing the point.
Sorry, new to regex and trying hard. Any hint appreciated.
