File size limit I can upload on my site ?

[hqt]

My account is "hqt" box7 . I use phpbb forum and I set limit file size my user can upload about 8mb but when I try to up a file about 4mb, I don't see any thing, I guess upload failed, a file smaller is successful. . But when I try to upload the same file 4mb via FTP is upload successfully. I don't know the error about my forum or limit file size host ? Somebody can help me about this problem. Thank you!
And this is a HOST excellent I have ever used

Excuse me for my poor English.

Hello! I'm also using phpBB for my forum. On mane page of ACP you can find something like Server information(PHP information) in the upper block at left. Click on it and find line upload_max_filesize - it's limit for uploading. Or you can create phpinfo.php file on server and insert code

 <?php
phpinfo();
?>  

Then open it in browser and find same line.

Thank you Amator, it is really useful to me I see upload_max_filesize 32M and I also find post_max_size is 2M, Is that why I can't upload a file larger 2M on post ?
So that setting is forced on sever or I can change it ?

It's setting of php.ini and you can't change it.
