There seems to be a conflict with permalinks between the Q&A plugin and the Events+ plugin. If I have the Events+ plugin installed, the permalinks for Q&A give me 404 erros (even if I change the permalinks and resave them, I still get the 404 errors). If I deactivate the Events+ plugin, and re-save permalinks, Q&A works.
For the time being, I've switched to a different event manager plugin but I would love to go back to Events+.
Thanks in advance.
