"HTTP Error" on Media after upgrade WP 3.5

Does the problem persist when you’ve deactivated the plugin?

no

why resolved? where is the solution?

i deactivated all of my plugins again and i found this:

My custom theme says “http error” without the plugins activated, also when Co-Authors Plus (Version 3.0.3) is activated with another theme (Twenty Twelve) it still says “http error” when i upload an image via media or post

Odd. Is it all photos or just some photos? Can you share some examples I can try? Who is your webhost?

the problem is with the dispossession of images.. specific any photo over than 511(width) i got http error , and any image less than 511(width) upload without any http error.

with wp 3.4.2 i don’t have any problem , only with wp 3.5

Have you tried it latest version of wp? Did you had the same problem? If yes, what is causing this problem wp 3.5?

Yes, I’ve tested with the latest version of WordPress and can’t reproduce. Considering there haven’t been any other reports of this, I suspect it’s a problem specific to your install.

hi

im change this file to .png, other format – have problem too

@zhivenkoff try this test

the problem is with the dispossession of images.. specific any photo over than 511(width) i got http error , and any image less than 511(width) upload without any http error.

i don’t thing is the file sizes but the dispossession of images

Ok, since we start from there lets take it all from the beginning .

When I still had the wp multisite at 3.4.2 version I didn’t had this issue. The site was working without any “http error” when I was uploading a photo through media or post/page.

After the update to 3.5 version it started giving http errors. I tried with with all the plugins deactivated and having activated only my premium theme. It kept having http errors, so I decided later to deactivate the premium theme and activate Twenty Twelve theme. It didn’t have any errors while I was uploading photos while all the plugins where deactivated. I decided after that to activate one by one the plugins and upload a photo everytime, when I activated Co-Authors Plus (Version 3.0.3) (while still having Twenty Twelve theme on) it showed an http error when I was uploading a photo. I started uploading many photo sizes, at first I thought that it uploads without any http error those that were smaller in size.
So, I compressed to a smaller size photos with big dimensions and it kept having http error. So I decided to upload photos with different dimensions and I saw the problem is with the dispossession of images.. specific any photo over than 511(width) i got http error , and any image uploaded less than 511(width) didn’t had any http error.

So with simple logic thinking, the premium theme and the plugin have incompatibility with wordpress 3.5 with the photo dimensions when you are uploading.

Also, I tried it only with CoAuthor plugin on Twenty Twelve and on my premium theme and I had again http error.

From this thread, it sounds like you might be having memory issues with your host. Co-Authors Plus registered four additional image sizes that you can disable with this:

add_filter( 'coauthors_guest_author_avatar_sizes', 'dbx_avatar_sizes' );
function dbx_avatar_sizes() {
    return array();
}
