Hey there. I've been testing your plugin on a local install of wordpress multisite (using two languages: Spanish and English) and it was working great; but I just installed it on my actual website and now I'm having major problems in the admin.
On the Spanish site, my edit screen doesn't load anymore! It crashes just as it's starting to load the multisite language switcher widget. I'm having the same problem on the all posts screen too. After ten or so posts get called up, the page stops dead.
As soon as I deactivated the plugin, everything went back to normal. To be sure, I also test the plugin with the default theme and all other other plugins deactivated, but the pages still broke.
I suspect it has something to do with the number of English articles I have on the site (over 1900).
Any suggestions? I'd really like to keep using this plugin.
