java.lang.NoSuchMethodError: com.atlassian.confluence.content.render.xhtml.Marshaller.marshal

Confluence server version in Linux has been updated to 5.1 to 5.10.9
(5.10.9 so that migration to cloud could be done, but not higher because license doesn't allow it)

Page links have stopped working.

There's directory "confluence-3.5.3-std" because Confluence has already once (many years ago) been updated from 3.5.3 to 5.1. There hasn't been problems with version 5.1, however.

Well, no, it won't help adding a jar to a path.  It's not the right thing to do.

The additional bit of log that you have now provided is actually pointing to an installed app, not the core of Confluence (and certainly not the jar you've jammed in).

That, however, is still unlikely to be the problem, as a failing app will rarely crash the entire system, 99.99% of the time, the apps just fail to load or run, while the core of Confluence works ok.

You could spend months going over logs and trying different things to try to get this to work, but the root cause is simply that your upgrade went wrong.

The best thing you can do here is restore the backup of your original system and try the upgrade again.

Adding confluence-5.10.9.jar to CLASSPATH didn't help

Nothing went wrong in update and Confluence (Tomcat) started normally.

Welcome to the Atlassian Community!

The first question is what went wrong in the upgrade and how you performed it?
