WordPress MU

Out of the blue i started getting an http error when uploading media, it just started this morning, i have been using 2.8.4 for over 2 weeks with no problems at all, anyone have an idea as to what this might be?

Thanks in advance, Tim~~

But which HTTP error is it?

Which error. all it says is http error while im writing a post,and uploadin media using flash uploader, works fine with browser uploader?

anybody have any ideas to why this is happening?

Anything in your apache error logs?

i think that sometimes the flash uploader causes problems.

Try allocating more disk quota for your blog uploads (Site Admin dashboard > Options > Blog upload space).

There are a few different threads going on this topic. I'm having this same issue. I'm getting the http error when using the flash uploader, but not the browser uploader.

I'm using version 2.8.5.2.

Sorry about the duplicate post... I some how posted in here twice. I'm just editing this post so I'm not saying the same thing again.

There are several threads for this issue. I'll list them below:

I finally got this issue fixed. Since I spent a whole day trying to get this resolved, I'm going to post the solution that finally worked for me.

Since some of the forum posts mentioned something about their host being involved, I decided to contact my host and see if they could figure it out and they did. I asked for details about what they changed so I could post it for other users.

Here is what they said:

"Modsecurity was blocking the useragent of the flash uploader. This is common. I disabled the block."

When I asked for more details about where exactly they made this change, they said:

"I simply removed the useragent block in /usr/local/apache/conf/modsec2.user.conf"

Hopefully someone else will find this useful.

Also, the last link in my previous post was not related to this topic, I posted it by mistake.

Anyway, I hope this saves someone else some time. :)

I am having the HTML Error when uploading video in WPMU installation. I have implemented the fixes in this forum and many others in the WordPress forums.

My hosting tech and I were working for most of the day on this. Still a problem. This is some of what we did:

1. Removed all plugins - yet the problem persists.
2. Reverted to the default theme
3. Got an error warning: "Cannot get media type from 'x-mapp-php5' " so moved the x-mapp to the ht conf file
4. tried AddType x-mapp-php5 .php to the top of .htaccess;
5. got several error messages "client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:)"

Does anyone else have any suggestions, please? This is very frustrating. Any help or suggestions gratefully received.

Sorry...that was an HTTP error (not HTML error:)). See it is doing my head in!
