Large file uploads problem

[Anon]

I'm trying to upload large (30M😎 files to my server. However, when I alter the php.ini to increse "upload_max_filesize" and "post_max_size" to 40M (is it correct to increase them both? Seemed to make sense...) I find that none of my forms that use the POST method (including the file transfering form) work--I just get the "Page cannot be displayed" error in IE after posting any data. However when I comment out my altered "upload_max_filesize" and "post_max_size" and restart my apache, everything works fine again (except the file transfers).

Any ideas on what I'm doing wrong or how to correctly enable large file tranfers?

TIA.

take a look at your apache config, i believe there is also a max_file_size for apache.

Solved it--just adding answer here for the archives.

I increased post_max_size to be larger than upload_max_filesize AND increased the memory_limit to be somewhat higher than post_max_size. Everything is working correctly now.
