Migrated from Windows to Linux, unable to manage plugins

I am testing migration from Windows based Openfire to Linux based.
Linux - Centos 8 (latest)
Openfire - 4.6.0
Centos minimal install, then downloaded and installed openfire.
Database on MS SQL server.

Setup wen OK
I modified names to reflect new host name
Went to Plugins section and install same plugins I use in Windows - OK

When I go to Server/Server Settings/Plugin name, I get 404 page not found.
“:9090/plugins/packetfilter/pf-main.jsp”
“:9090/plugins/contentfilter/contentfilter-props-edit-form.jsp”

I tried to install plugins through GUI and by uploading .jar files. same results
I looked in folder and indeed there are no .jsp files.

What am I missing?

Thanks

thank you.

I assume versions prior to 4.6 are OK?

Any chance that compatibility with older plugins be added in later versions of Openfire?

Some extremely useful plugins may be left out like PacketFilter plugin; was updated last time in 2015.

There is a recent snapshot of Packet Filter plugin here https://www.igniterealtime.org/projects/openfire/plugin-archive.jsp?plugin=packetFilter
And it had this commit which should fix the 404 error issue https://github.com/igniterealtime/openfire-packetFilter-plugin/commit/28047455691016f8dce3033f87575eea10bca63f
So it seems just a matter of time for someone to release new version of this plugin. Meanwhile you can download the latest snapshot and try installing it, see if it works ok.

@akrherz has released version 3.3.1 of the PacketFilter plugin moments ago. Its admin console pages work for me, in Openfire 4.6.0. Can you test if that resolves the issue?
