I want to change the
upload_max_filesize = 2M to
50M, then I started edit on php.ini, but when try to save it, it displays error message below
Could not create a backup file while saving /etc/php5/apache2/php.ini
gedit could not back up the old copy of the file before saving the new one. You can ignore this warning and save the file anyway, but if an error occurs while saving, you could lose the old copy of the file. Save anyway?
