Cythe changes since ou most likely would not have the authority. On a Linux box determine what php.ini file your php is using. Do this with a file called junk.php for example. It should look like:
Place junk.php in your WordPress root directory.
In your browser of choice enter: http://www.yoursite.com/junk.php
This will output a lot if data if your php environment is functioning properly. Look for the following:
php.ini – the path to your php.ini file will be here.
vi your php.ini file (noted in the above output) looking for “upload_max_filesize” and change it to what you think you need, i.e., 33M. Restart apache (sudo service apache2 restart) to pick up the new value. Look at “http://www.yoursite.com/junk.php” (may need to force a refresh) to see your new “upload_max_filesize” value. This should correct your 2M limitation.
I have seen a lot of posts where many have changed this value in their php.ini file and “nothing happens”. I am assuming that this is because the apache server (or whatever they are using) is not being restarted to acquire these new values.
Hope this helps.
