Uploading large files fails silently

Hi,

On a mediawiki 1.15.1 linux installation, I can upload files smaller
than 8 MB without problem.

With files >= 8 MB, once the transfer is complete, I am brought directly
back to the Upload form, which is empty. The uploaded file is not in the
images/ directory and not in the list of new files. This is 100%
reproducible. No error is displayed either on the page, or in the apache
logs.

I also had the problem with 1.14.0.

- The maximum php upload size is 40MB so that's not a problem.
- I tried increasing max_execution_time and max_input_time in php.ini.
These timeouts are definitely not reached.
- I tried doubling the maximum memory usage of a php script (now 256MB).
- Updated to the latest apache and php5 from debian testing.

Any ideas?

Thanks

pmf

What is your setting for post_max_size

Cheers,

8 MB! This was exactly the problem. It would be great if an error
message was displayed somewhere when this limit is exceeded...

Thank you so much.

Check php max post size.
You're sent to an empty upload form because mediawiki isn't even seeing
the data you sent. Php is filtering it.
