I was thinking of implementing a "related articles" feature into my bilingual site and yours came up on the top of the plugins to try following my research here on wordpress.org.
Ok, that was the good news. The bad news is that I have determined that your plugin does not seem to be compatible with my main plugin (wp_multilingual). As soon as I enable your plugin (Similar Posts) I can no longer call up my site. And yes I did have the secondary plug-in installed.
I am able to set all kinds of parameters - so the plugin seems to be working ... but as soon as I click on "Visit Site" - bang oh, dead! Eventually Firefox comes back with an error saying it is in a redirect loop and has stopped trying to load the site.
Is there some way to can sort this out with Oleg (authour of wp_multilingual) or do I need to look at another plug-in?
Looks great and most everyone has good things to say about your plugin - but for me it's not an option if I can't get it to work with wp_multilingual.
