Our install (2.5.0.beta2) is having a couple of issues with the quote feature in replies:
Issue 1 - The quote is working intermittently. Users are experiencing times when the quote shows up briefly and then disappears upon replying. I’ve seen this behavior myself but it is difficult to reproduce consistently.
Issue 2 - Quoting a reply that itself is a quote does not return the proper author in the parent quote. Please see the example provided here:
Any ideas what might be causing these issues?
