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 had this issue. With google chrome browser many times when it was loading my site or a post/page from it it was giving me this message “oops google chrome could not find ….”. On Firefox it said “The conection has timed out”. Although 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 dimensins when you are uploading.
p.s.#1 The problem with Chrome and Firefox continues at the update on the version 3.5. Which is the reason of this problem and how it can be fixed?
p.s.#2 On the wordpress multisite 3.4.2 version with subdomains you must have .htaccess and Mod Rewrite
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]
# END WordPress
and on 3.5 version
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) wp/$1 [L]
RewriteRule ^(.*\.php)$ wp/$1 [L]
RewriteRule . index.php [L]
so after the update I have to change it? I made a test and it dissapeared all the photos from the site. Is it normal?
