Hi @yen0727
We sincerely apologies for what happened and that your site went down.
The crash happened for some sites who use caching functionality and
when updating from version 3.2.3 to 3.2.4 using auto update feature.
As soon as we are aware of the problem, we released the
fix in version 3.2.5 same day.
That said, we have reviewed our testing process to make sure releases work in
every environment to ensure it never happens again.
