Im not sure the what the best way to fix this or what the real problem even is but here we go.
I have been setting up a nonprofit site and i bought the event calendar pro plug-in from Code Canyon
This plug-in works with all my other plug-ins installed and configured. But when I turn on the "Automatic follow up emails for new users" plug-in or the "Blogs Directory" plug-in the single event listing pages turn into 404 not found. All the data is still there. If i remove the two plug-ins, the calendar plug-in works again.
From what i understand, the problem might have to do with the permalinks. Im also going to open a ticket at the other plugin sites.
(link to other plugin forum where i have been asking questions:
Please Advise as to what info might also be helpful to fix this problem. Should i open a new ticket on the blogs plug-in page too?
Thanks for all your help,
