Server issue Double Posts

[swatme]

i am experiencing and other members double posting after upgraded to 1.0.3

after typing message in the thread,
then click submit, nothing happens.
so your thinking you didnt click the submit,
you click submit again.

after you click the refresh button, there its double posts already.

Just a pure guess here, because this was happening on lots of forums when IE 9 came out. MyBB had to create a fix for it in a later version, as well as IPB with the new IE browser causing double posts to be submitted on forums.

Worth looking into anyway, you never know, might be the culprit at play here.

For me, and just my entries in Personal Conversations, this is a rare occurrence in FF5.
With the timestamps being identical, I'm more or less leaning towards that it's simply a server niggle.
Given that, it could happen on any platform. Heck I even get double posting on Facebook so

The one time that this happened it was spaced out in a matter of 1 minute, 10:41 is the first post and 10:42 is the 2nd . Oddly enough the merge post mod didn't merge it so I believe it is what people are stating that it is a server side issue. I can't see why at this morning's post because I have a low server load at that time.

Recently moved to a VPS.
No reports since.

Same here - also when you hover over the Alert or Inbox it tries to return the info, but it never does.

I have been on the same server box for years, so I am sure it is not the latest and greatest. May look into upgrade

my users reporting the same error today. Any chance for guidance, where should I look at to get it fixed ?

Guesses:

1) A spotty connection to the server resulting in automated attempts to resubmit the request, possibly resulting in double posts.

2) A failed or slow connection to the SMTP server resulting in slow posting times (notification emails are sent on reply). Slow posting times will often lead to users clicking the submit button multiple times when they think the post didn't go through.

My first guess would be #2. I have seen this be the case for some other admins. #2 would require you to look at your SMTP server, and possibly use a different SMTP server. Here is a guide for using Google as your SMTP server:

Actually, you can test #2 by disabling mail functions to see if that fixes the issue:

library/config.php

Add this code:

$config['enableMail'] = 0;

If that fixes the problem then you know it's the mail server at which point you can look at your SMTP configuration and possibly try a different mail server.

Is it possible that this could be occurring even though there are no entries about it in the server error log? I'm seeing delays and double posts on big threads which many people are subscribed to. Disabling mail functions using the code above seemed to help a little but not entirely.

Server is not struggling with cpu or ram that I can see. Pages load quickly. Mail server is exim mta, set up using this guide. Email Transport Method in xenforo options is "Default" with -f parameter checked.

Are you using Tapatalk? There are reports of double posting problems caused by Tapatalk:

http://xenforo.com/community/threads/upgraded-to-1-1-3-from-1-1-2-double-alerts.35861/

They say you can downgrade to an older version to fix it:

Do not disable it, just downgrade to version 1.1.4: http://tapatalk.com/files/plugin/tapatalk_xf10_1.1.4.zip

You know too much. I was just thinking that my first step in troubleshooting this should be to disable addons. Whoops. Sure enough, disabling Tapatalk appears to have resolved this issue.

Thanks, Jake. You are an incredible asset to xenforo.
