Bug: Can't save pages when using MySQL version older than 5.6

UliCMS 7.2.1 contains a bug, that prevents the save page function from work, when using a MySQL Version older than 5.6.

To fix this please execute following SQL statement in PHPMyAdmin or sql_console

ALTER TABLE ulicms_content add custom_data varchar(255) NULL DEFAULT '{}';

Maybe you have to adjust the table prefix.

Update:

An updated installation package which contains a fix for this issue was released.
