[Koha] How to resolve bug Bug 28267? What must I do in mysql?

[Δημήτρης Δαλαγιώργος]

Dear all,

I'm not a developer, and as I mentioned before, I'm stuck with an
inoperable library catalogue due to the fact that I can't update to
the latest version because "Older databases fail to upgrade due to
having a row format other than "DYNAMIC"".

I've read the comments on this bug but I fail to understand what I
should do to fix this. Obviously I must login to mysql and perform
some actions. What actions are those? Can someone point me to detailed
instructions?

Kind regards,
