Update:

I’ve isolated the duplicate posts issue to some kind of interaction with the YD Domain Mapping plugin. We’re using this so that we can map arbitrary domains to our network sites.

E.g.

1. our WordPress Network is set up as wp-network.foo.com, on a subdomain setup
2. a network site ‘bar’ would then be bar.wp-network.foo.com
3. we setup the feedwordpress plugin to pull in posts from a tag:uri feed
4. we get unique posts in, with GUIDs of the form bar.wp-network.foo.com?guid=(some guid)

All well and good. BUT, then we use the domain mapping plugin to map blog.bar.com to that network site…

It seems that when we hit a network site on its mapped domain (blog.bar.com), it instantly duplicates the syndicated posts with guids of the form blog.bar.com?guid=(the same guid)

I set up 2 identical blogs, subscribed them both to the same feed, and applied a domain mapping to one but not the other. All was fine until I hit the blog homepage on the new mapped domain- at which point all the posts got replicated with mapped domain GUIDs as above.

So I don’t know if this is an issue with FeedWordPress or with the YD Domain Mapping plugin, but they definitely don’t seem to play nicely with each other.

Hope this helps!

Hi,

I’m using WordPress 3.3, and I’ve upgraded to feedwordpress-2011-1019 , and I’m still getting duplicate posts on every update. I’m not using HTTP auth, but the feeds are using the tag URI scheme for GUIDs

Ah-hah!

I think I’ve fixed it, by logging onto the MySQL console and running
repair table xyz for each table in the WP database.

It didn’t show any problems, but since running that, I can now publish the posts that I previously couldn’t.

Note that I had previously run the command-line myisamchk utility, and that didn’t fix it, I had to manually do a repair table.

Thanks a lot for your suggestions, and hopefully this will help anyone else with the same problem.

Hi,

Thanks for the suggestions, I appreciate it. Clearly something must have changed, but it’s proving very difficult to find out what it is…

The issue started about 4pm (London time) this afternoon. When I search in the wordpress directory for files modified in the last 24hrs, I just get the uploads directory for September – which is empty:

> find . -mtime -1 -print
./wp-content/uploads/2011
./wp-content/uploads/2011/09

>ls -larth ./wp-content/uploads/2011/09/
total 0
drwxr-xr-x 4 www-data www-data 24 2011-09-01 08:35 ..
drwxr-xr-x 2 www-data www-data  6 2011-09-01 08:35 .

So no wordpress files have been modified recently. Also, I have no error_log files in there. The Apache error log shows nothing relevant, just 404s from the browser requesting a favicon.

It’s not a Javascript problem, the Chrome JS console is good at detecting those and acting like a debugger, and it shows nothing. None of our writers or editors use Internet Explorer.

There’s not much to go on, I know…

However, I have found that I *can* publish a really old test post, from a few months back. I just can’t publish anything from this afternoon onwards – and yet there’s no visible difference between those posts.

I did notice a strange thing when it first started happening – I got a message saying that I couldn’t edit a post because another editor was already editing it, although she definitely wasn’t (she logged out and closed all her browser windows to make sure).

Thanks for your help,

Al

Hi ce_kevinw,

Thanks – but that was the first thing we tried. I’ve tried it on Chrome & Firefox on Windows 7, and Chrome and Opera on Ubuntu 10.04.

It’s very strange
