Hi there,
Firt, i like your plugin, it's great.
Second, i have one problem and i need your help.
I use a polylang version 1.6.1 and i never had the two plugins working well together.
The problem is: if i add a user created by a wordpress, the co-authors show the articles of that user, ok, sounds good, but if i add a user created by a guest method and click to get the articles, i received a 404 page.
Note: If i disable the polylang, everything works great.
thanks in advance
