I did a search on the topic but couldn't find anything more than a few months old, so...
On the installation & Use Instructions for the Classifieds plugin it says if Classifieds is activated with Directory (or CustomPress) you will receive a fatal error, but it will be "fixed for the next version release."
I'm not sure when those instructions were posted (version release), but the current version is 2.0.9.
So I was wondering...
Has this been fixed as of the current release?
And if so, is it a safe assumption then that both plugins can be used concurrently:
...on the same site (single installation or network)?
...on different sites on the same network?
If so, is it also safe to assume it will now work with CustomPress as well?
I have actually activated both Directory and Classifieds on a single site on the same network and didn't get the fatal error - but then I haven't yet set up either one or imported the taxonomies or custom fields in Directory (which may be why it seems to be working for now).
Thanks for your help!
