Optimus error when creating sitemap

[TonyJ]

When I click SAVE in the SiteMap screen, nothing happens. No sitemap file is created, or at least, I presume it's supposed to drop it into my root folder?

When I click the Sitemap footer link, a 404 appears.

I'm using SMF 2.0.18
Optimus 2.7.1 [16.02.21]

Thanks for any help.

is this the mod you are referring to? https://custom.simplemachines.org/mods/index.php?mod=2659

make sure what setting you have for it to "add to the sitemap only those topics that have more than ___ replies" if you have this number as let's say 5 but a topic has no replies, it won't be added to the sitemap.
If that is not the issue, then please post in the mod's support topic.
