WordPress ignoring php.ini upload max file size

Question

I'm running a WordPress site (not MU), I have set upload_max_filesize = 50M, post_max_size=50M in php.ini. The results of phpinfo() function show the value to be 50M but in WordPress Media uploader Max upload file size is still 32M.

I have also tried to write this code in the theme's functions.php:

@ini_set( 'upload_max_size' , '50M' );
@ini_set( 'post_max_size', '50M');

Also tried deactivating all plugins, changed theme but no resort, WordPress still says 32 Mb.

Can anyone guide me what can be wrong here?

Answer 1

I had the same problem, and the other answers didn't completely work for me, and I'm apparently not alone, so here's what I did to make it work.

1. Locate your php.ini files: sudo find / -name "php*.ini" -print. This will give you an idea of where any configuration files might be hiding.
2. Open them one at a time (you may need sudo).
3. Check to see if they have a line "upload_max_filesize=##" where ## is some value (i.e. 250M). You shouldn't have to add any of the lines. This should already be in the file.
4. You will need to change the line "post_max_size=##" to be greater than or equal to upload_max_filesize.

Notes:

Supposedly, you can do "php -i | grep php.ini" to see which configuration file is being used, but changing the indicated file did not work for me. I changed one that lived at /etc/php5/apache2/php.ini to make it work. Some trial and error will be needed, but give this a shot.
