I have two completed famous models (11749783 and 11749773) with several zip files that will not upload due to this error:

Project file upload handler is missing

What does this mean? I cannot upload anything.

It means that the URL in your client_state.xml file is wrong, probably because the mystery mis-spelling bug has struck, or that one of the file_upload_handler aliases has not been defined in httpd.conf for this server.

It's very annoying that BOINC client says that the file_upload_handler is missing, which is not the case here.

Looks like it's trying and getting 404:
http://kraken.oerc.ox.ac.uk/cpdn_cgi/file_upload_handlrr
and
http://kraken.oerc.ox.ac.uk/cgi-bin/file_upload_handlrr

Found this thread on the issue:

Replaced the handlr with handler
Replaced the handlrr with handler
...for all zip files in client_state.xml.

Uploads are going finally.

If you are getting "Project file upload handler is missing"

Do: shut down boinc manager and boinc. Do a backup.

Then: edit the BOINC/client_state.xml replacing all misspelled handlr or handlrr or whatever with "handler" like DJStarfox said.

Start BOINC again -- uploads should work -- did ok by me.

Thanks - apologies for not getting back to you faster.
