Hello everyone!
We are running our wiki, mediawiki version 1.42.0-wmf.23, PHP 8.1.2-1ubuntu2.14 (fpm-fcgi), MariaDB 10.6.16-MariaDB-0ubuntu0.22.04.1-log.
Lately when we import any article that contains citations such as { { cite book } , { { cite journal } } etc.. for example it contains a line like the following "{ { cite book | title = test book } }",
Instead of displaying "test book" it generates a lua error :
Lua error in Module:Citation/CS1/Configuration at line 2058: attempt to index field '?' (a nil value).
Backtrace:
- Module:Citation/CS1/Configuration:2058: in function "init"
- package.lua:103: ?
- (tail call): ?
- mw.lua:496: in function "executeModule"
- mw.lua:768: in function "loadData"
- Module:Citation/CS1:4394: in function "chunk"
- mw.lua:527: ?
- [C]: ?
We have been using mediawiki for more than 6 months and this issue only happened in past month.
I appreciate any guidance to identify the problem and solve it.
