wpMandrill

There is a conflict with the wpMandrill plugin. If you want to use RBE, but still use Mandrill to send out email, follow these instructions:

WP-SpamShield Anti-Spam

If you are using RBE in Inbound Mode with WP-SpamShield, Mandrill's webhook might fail to post back a response to the server:

If you want to continue using WP-SpamShield with RBE in Inbound Mode, make sure WP-SpamShield's Disable anti-spam for miscellaneous forms option is checked.

2) Check debug log

If you've connected successfully, but still haven't seen your post, RBE comes equipped with a debug log.

You can view this log by navigating to /wp-content/bp-rbe-debug.log on your server.

Note down any errors you find and either post a new issue publicly or contact me privately here.

3) IMAP Mode

I'm using GMail and have entered my login credentials, but I am always seeing the "Reply By Email is currently NOT CONNECTED. Please refresh the page to initiate a connection." notice on the RBE settings page

This issue is caused by GMail's increased security settings.

1. Open your web browser and login to GMail with the credentials you are using for RBE.
2. Now, visit this page:
   http://www.google.com/accounts/DisplayUnlockCaptcha
3. Click on the blue Continue button.
4. Next, go to RBE's settings page and click on "Save Changes" so RBE will initiate an IMAP login attempt.
5. Now, RBE should say it is Connected.

I replied to a RBE email, but it hasn't posted on my site yet

Here are some things to try:

(1) Does your site generate enough traffic?

Read this FAQ for more info.

(2) Did GMail mark your reply as spam?

If you're using GMail, see if GMail marked your reply email as spam. Login to GMail with the credentials you use in RBE and check the "Spam" folder.

If your reply email is in there, then that's the reason your reply was not posted onto the site.

(3) Are you on a shared host?

If you're on a shared host, you will not have the most optimal performance.

You should use Inbound Mode.
