[MediaWiki-l] Scribuno / Lua problem

Peter Presland
I have hit a problem with the Scribunto extension which, after a good
few hours digging,  I have not been able to  track down and fix. It
manifests as an 'Internal server error' with the message ' The server
encountered an internal error or misconfiguration and was unable to
complete your request.' , but only when completing or previewing an
edit. All affected pages still work fine except that their main template
cannot be edited (The pages themselves can).

The site uses about a dozen big and complex Semantic templates, each
including up to twenty additional templates plus calls to the standard Wikipedia
'infobox' Lua module. Trying to complete or preview an edit to that
module separately produces the same error aswell.

I can find no related entries in the http error or any other log and the
Infobox module last edit date predates this problem by at least a year.
It therefore looks to me like a Linux server config issue of some sort,
although I cannot recall any changes there that pre-date the problem either.

Can any one offer any ideas please.

Peter Presland

I would agree with that, but unfortunately that's not the sort of
issue we can easily advise upon as it depends on a myriad of factors,
such as what OS you use, what webserver software, what database server
software etc. You would need to ask your host or sysadmin to
investigate that. If you don't have one, you could post about this on
a Linux forum perhaps, or considering hiring a Linux consultant to
troubleshoot.

In reply to this post by Peter Presland
A couple of months I had to reconstruct the Wikispooks site from backups
and had to accept the  loss of a few days edits as a result. I suspect
that the reconstruction process is at the root of the Lua/Scribunto
issue because it was also necessary to use a new Linux (Centos 7) image
for the vps and it is therefore quite possible that some obscure but
critical Linux or php config setting was lost/changed in the process.

So, can anybody point to a server module or config setting that is known
to affect Scributo/Lua editing and that is not readily apparent from
existing MW and Lua documentation? - which I have studied exhaustively
though NOT to say that I have not missed something glaringly obvious of
course - as you do :-))

Thanks in anticipation
