Updating Olinda child theme to v2.2.2 and old insecure Revolution slider.
We're currently running 2.1 version of the Olinda child theme.
We have recently have a hacked
WP installation of the Jobroller/olinda version we are using for a client. I'm just going through to make sure that everything is as up to date as it can noticed that olinda has a newer version.
With a bit of digging the Revolution Slider is version 2.2.3. There is a security vulnerability with any version 4.1.4 and below and must be updated straight away. The Revolution slider does not update with the child theme as with our other websites. We need to do this asap.
Also how do we upgrade our version of Olinda to latest version. It's a child theme so not sure how we go about sorting the upgrade without overwriting our work.
Regards
Paul
