Media upload error wordpress 4.0

Sounds like a permission issue on the /uploads directory. I’d check with your host and make sure permissions are correct and then try again.

Possibly could be due to upload limit but if it’s happening on all images (all sizes) then I’d guess permissions.

I don’t believe this is a permissions problem. One of my sites was fine until they pushed the 4.01 update and now I get the same error. I checked permissions on my October folder and it’s the same as my November folder, CHMOD – 755.

Someone needs to troubleshoot this quickly and come up with a fix. I can’t (and many others I’m sure) upload any media files!

STRANGE, it just began working for no reason…

My issue resolved itself somehow since my post.

HeadMonkey,

Thanks – but this issue was reported before 4.0.1 was released so I doubt it’s related.

The dread HTTP error, in no order:

* ImageMagick is broken
* Your server’s /tmp folder is full (or you don’t have permissions to write to it)
* The image processing by ImageMagick is overrunning your PHP buffer

Check your server’s PHP error logs.

(If it was permissions on the uploads folder, it would actually tell you that)

I have given all permissions to uploads folder, but still facing the same problem.

This is not permissions problem.

I’ve just today completed a fresh install of 4.0.1 and am unable to upload images. Uploading generates an http error but doesn’t give any information on what the error is.

Not experienced this before with several 3.x.x WordPress installs on the same server base.

Any ideas??

I am now having the same thing happen with 4.0.1 that I have never had happen before the upgrade. And I can confirm it is happening on multiple sites. Is this a bug in the release? Are there new restrictions on image dimensions?

I was having the same problem for a while and I MAY have solved it (but still need to do some further testing) so I thought I’d post a reply in case it’s helpful to others.
Before upgrading to the latest version of WP I had WP Super Cache installed. Since I had to do some troubleshooting after the upgrade, I had disactivated WP Super Cache. Since someone mentioned the /tmp folder, I thought maybe temporary cache files would have something to do with it. I re-activate WP Super Cache, cleared the cache, and was then able to upload images.
I’m not an expert on this kind of thing, so am not sure whether this is actually what got it working, but it seems to have fixed it for me!

I was running into this, had OBox activated, turned off, all good now. Wondering if anyone else experienced this…

ZOMG eberlyjm, thank you so much for posting your apparent solution. We had the same problem, where the “Site #1” of our multisite install could upload and crunch image files just fine, but all the sub-sites (in subdomain structure) were failing the ImageMagick crunching/resizing etc. The files would load onto the server in their appropriate folder, but we would get “HTTP error” and they would not process properly for the media library.

I went into our WP Super Cache settings, clicked “Delete cache from all blogs,” and voila–after weeks of Google rabbit-holing to no avail, the problem is solved!!
