Re: Issues while trying to upgrade from 18.4 to 20.0 a site using tikinewt theme
I know that MySQL 8 came out a year ago, but when installed MySQL recently (a couple of months ago) on a local Ubuntu system, the default install is still 5.7.
In theory 8 version should work with Tiki but if you haven't done so already, it may always be worth asking the Tiki development teams if Tiki already supports version 8.
