Hi,
Sometimes somes fields are not added depending on the mysql configuration.
Can you try to run these 2 queries on your updated database please ? :
ALTER TABLE `networks` ADD `MTU` VARCHAR(255) NULL DEFAULT NULL AFTER `SPEED`;
ALTER TABLE `download_available` ADD `DELETED` INT(1) NOT NULL DEFAULT '0' AFTER `ID_WK`;
Reload your apache 2 service and try again :)
