Please update your version of MetaPhlAn?](https://forum.biobakery.org/t/humann-3-9-conda-install-will-not-work-please-update-your-version-of-metaphlan/8484): > > I installed humann3 according to instructions using conda. but there is an incompatability in the versions.

This is unfortunately a necessity otherwise we’d have a lot of spam on the forum… Common causes of false positive flags are 1) typing your message elsewhere and then copy-pasting it here (Discourse sees this as “typed too fast” and thinks you are a bot) or 2) posts that are almost all code/log with no English sentences describing the issue. Hope that helps going forward! --- _[View the full topic](https://forum.biobakery.org/t/error-the-metaphlan-taxonomic-profile-provided-was-not-generated-with-the-expected-database-version-please-update-your-version-of-metaphlan-to-at-least-v3-0/8485)._
