WordPress Spanish 3.1
Although the translation for WordPress 3.1 release was already available we discovered that there were errors, beyond our possibilities, because as we have said several times the translation team only has access to the system of translation, not the composition of the nucleus (core) of WordPress or system updates.
Well, fortunately is now fixed thanks to the intervention of Rafa Poveda, so if you already upgraded to WordPress 3.1 in Spanish of Spain, to fix the flaws of translation, you just have to go to the updates page and click on “Automatic re-installation” so that it loads complete and correct translation.
Of course, it is already loaded on the official site of WordPress Spain. However, as always, this is a constant work and if you detect an error in several places you do not fail to comment and fix it.
