When new user tries to create new post with more then 2 links then he receives “Internal server error”. I found in /var/discourse/shared/standalone/log/rails/production.log the following: ``` Completed 500 Internal Server Error in 76ms (ActiveRecord: 12.5ms) I18n::InvalidPluralizationData (translation data {:zero=>"Bohužel, návštěvníci nemohou vkládat odkazy do příspěvků.", :one=>"Bohužel, návštěvníci mohou do jednoho příspěvku vložit jen jeden odkaz.", :other=>"Bohužel, návštěvníci mohou do jednoho příspěvku vložit maximálně %{count} odkazů."} can not be used with :count => 2) /var/www/discourse/vendor/bundle/ruby/2.0.0/gems/i18n-0.7.0/lib/i18n/backend/pluralization.rb:35:in `pluralize' ``` I have installed the latest version of discourse (latest-release +140, 1.4.0.beta12).

Well, actually it’s a problem in the English locale file that’s causing this. `server.en.yml` contains the `zero`, `one` and `other` keys, but according to the [official pluralization rules](http://www.unicode.org/cldr/charts/25/supplemental/language_plural_rules.html#en) only `one` and `other` are allowed. It currently works for English (and all the other languages that use only `one` and `other`) because the Ruby I18n module has a [special case for the `zero` key](https://github.com/svenfuchs/i18n/blob/master/lib/i18n/backend/base.rb#L133-L135). > Unfortunately Transifex doesn’t handle the special case of `zero`, so it doesn’t detect any key as pluralized if there exists anything else than `one` and `other` in the English locale files. That’s the reason why the `server.cs.yml` contains the `zero`, `one` and `other` keys instead of the [required `one`, `few` and `other`](https://github.com/discourse/discourse/blob/master/config/locales/plurals.rb#L16). > There’s currently no easy way to fix this. I was planning on proposing a few solutions to this problem in the next few days. ---

Simplest fix is just splitting this translation, so zero has its own key `no_links_allowed` `too_many_links` problem solved 🙂 ---

Yes, splitting would be the easiest option. There are about 20 keys with this problem, so that shouldn’t be that much work. ---

How can I patch our code to address this problem? I would put there something really simple _‘Too much links in your post. Try to remove few of them. Sorry.’._ ---

You’d need to manually add the missing `few` keys in `server.cs.yml`: > Don’t forget to use the `%{count}` placeholder for those translations. * * * I’ll try to create a patch for this in the next few days unless someone else wants to do it? I’ve already implemented some tests to guard against the usage of the `zero` key in English locale files. ---
