Thanks for the info. In order to figure out what is generating the error 500, you’ll need to follow the regular WordPress debugging steps:

1. Enable WP_DEBUG and WP_DEBUG_LOG, and check wp-content/debug.log file after triggering the error;
2. Check your hosts error logs for clues;
3. Disable all plugins except bbPress, bbPress Notify (No-Spam) and Reply by Email;
4. Re-enable other plugins in small batches and see which ones are causing the conflict;

Cheers,
Vinny
