Script error in [[Template:pl-decl-adj-i]]

This template has been triggering a script error for a while now. I tried to fix it, but nothing seems to work. Can you do it please?

Nothing seems to work, because you have not read the error message. The module tried to inflect the adjective "pl-decl-adj-i" according to its database of inflection patterns, but there is no match, because all patterns try to match a consonant before the final vowel(s), and "-" is not a consonant.

I just restored the November 2012 version. Should work just like before conversion.

I did read the error message and I'm a bit annoyed that you assumed I didn't. I tried to fix the problem by overriding things so that it would use "-ni" as the word instead of "pl-decl-adj-i" but my override was ignored by the module.

I stand corrected. It seems that the override actually works. Maybe you forgot to purge the cache.
