You may be able to set those values from the cwp admin panel.
Use
PHP.ini configuration under main menu.
A more easy configuration of those two commands can be done using menu PHP Settings -> Simple editor._________________________________________
You didn't answer me.
Which setting did you change? You say:
import file size
which is not a value name of the php.ini values.
You should open the current php.ini and set 2 values, not just one.
post_max_size=100M
upload_max_size=100M
On wich file did you make the changes?
Mine is at /usr/local/php/php.ini path.
