Today Dreamhost fixed the issue. Turns out that there was a large file in my tmp directory (which PHP uses to handle the uploads) that was using up 100% of the capacity and therefore other uploads failed. The trick is that the tmp directory is outside the available folder structure for most shared hosting accounts, so Dreamhost needed to empty out the folder by hand. Once they did that, the uploader seems to be working like a charm!

So bottom line: try contacting your hosting company and having them clean out the contents of the tmp folder that PHP uses for uploading.

As a side note, I wonder if there was anything in the updating process that could have created that huge file, because none of our users tried to upload a huge file…

Update to this post. I have tried the following:

1. Completely deleted all WordPress files and re-uploaded from a fresh download from www.ads-software.com
2. Added mod_security permissions in htaccess
3. Disabled mod_security on the server
4. Changed htaccess to be just the native htaccess code that comes with WordPress
5. Double checked all folder permissions
6. Uploaded different files to see if it’s related to my test file (all file sizes below 1MB)
7. Attempted upload from both the post interface and from the media area
8. Attempted to upload using both Flash and standard browser buttons. Neither work. Flash returns an HTTP error (no other info) and the standard browser upload button returns an “internal server error”
9. Begged the Gods for help

No joy on any front.

Checking the error logs, I receive the following (IP address and hostname hidden for security):
[Thu Apr 14 13:11:46 2011] [error] [client 555.555.555.555] ModSecurity: Input filter: Failed writing 8192 bytes to temporary file (rc 18446744073709551615). [hostname "hostname.com"] [uri "/corporate/wp-admin/async-upload.php"] [unique_id "TadVAa3s33IAAGmoDMgAAAAA"]

So questions that I have:

• How much CPU usage should uploading a 500kb file take?
• Is there anything in the WordPress 3.1.1 media uploader revisions that would create this type of error?
• What are possible causes for failures to write a temporary file?
• Is there anything else I can try or any other diagnostic I can use to get a better idea of where this whole system is breaking down?

Thanks in advance,

Oh – I should say: I can’t upload from anywhere – post, media page, etc.

I’m getting this as well. What hosting company are you with? I’m with Dreamhost on a VPS. The latest they told me is that my WordPress install is using a crazy huge amount of CPU and that the upload process (for a 225kb file) is spiking over our limit and therefore being stopped. Somehow that sounds a bit wacky to me.

I’m wondering if the “hardening of security measures in the media uploader” has done something which causes problems on with some hosts?

Same issue, although mine only shows one quote.

I installed the plugin, added two quotes, installed the widget. Then deleted the two initial quotes, added two more, and only one quote out of all three shows.

I’ve tried deactivating/reactivating the plugin, deleting & reinstalling the widget, removing the character limit, etc. Any ideas what can be done?!

I’m getting the same problems. Does anybody have a fix?

Does anyone have any solutions for this? I’m reading around and it looks like this problem crops up when WordPress is installed in a subfolder (not in the root of the site).

Does anyone have any ideas on this? I’m having the exact same thing…
