CC-BY-SA enhances the CC-BY license which claims that the creator(s) of a cultural work aka the licensor(s) shall be named as such in any shared copy or shared recording or actual public performance of the work, for any new variant of it. That's the meaning of the BY-clause. The SA-clause aka ShareAlike clause means that any sharing of the work or variants of it MUST be licensed in the same way as the CC-BY-SA does. Therefore You must know:
Only the early license version 1.0 of CC-BY-SA obliges to share the work or variants of it also under CC-BY-SA 1.0. Of course that first license version is completely outdated because it's designed just for the USA.
The version 4.0 of the CC-BY-SA license is, according to creativecommons.org, upward compatible with the CC-BY-SA license versions 2.0, 2.5 and 3.0 !
If any new cultural work in this wiki is designated as CC-BY-SA licensed w/o version number, we and any user of the wiki must suppose that this means at least CC-BY-SA version 2.0. This assumption allows to create variants to be shared in the license variants 2.5, 3.0 or 4.0 since they are officially declared upward compatible to version 2.0 by creativecommons.org
If You are not the creator or licensor of a free work that you publish on this wiki, but that work had the CC-BY-SA license version 1.0, then and only the you must share it here unter that outdated license version and none other.
