POST Content-Length of X bytes exceeds the limit of Y

I know the problem is in "post_max_size = 8M" and I changed it to 128M but the error message still says 8M.

What I did change:

php.ini
post_max_size = 128M
upload_max_filesize = 128M
max_file_uploads 100

or

.htaccess
php_value post_max_size 128M
php_value upload_max_filesize 128M
php_value max_file_uploads 100

The old ci v3 works fine and the ci v4.2.6 didn't.

PHP Code:

<br />
<b>Warning</b>:  POST Content-Length of 8480241 bytes exceeds the limit of 8388608 bytes in <b>Unknown</b> on line <b>0</b><br />

What does phpinfo() output?

To apply the php.ini changes, you must restart the server

PHP Warning: POST Content-Length of 8978294 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

What did you Try? What did you Get? What did you Expect?

Joined CodeIgniter Community 2009.  ( Skype: insitfx )

Now I noticed, because the "php spark serve" is connected.
When I changed php.ini on the server and tested "phpinfo" inside the project and it didn't change. It's because "php spark serve" is connected, I turned it off, back on and everything is normal.

"php.ini" works fine but "htaccess" doesn't work or change.
