After upgrading, all setting gone and my clients can't use the internet from previous vouchers and I have to setup all things online  again whole night. I got new problem on portal mode, "create vouchers" made me confuse. There're 2 choices "Limited Usage Counts" and "Limited Online Users" but after vouchers created the first one shown TYPE as sand clock icon with hover text "Valid for 1 user" and another one shown TYPE as user icon with hover text "Valid for One-Time use". All these right? Please correcting these problem. Thx.
