How can we remove a protection from a page?

Hi, Siebrand, how are you? I'd like to ask you how can we remove a protection from a page, specifically this one. Because the expression Diklitera teksto is NOT Ido, it's Esperanto! I'm a collaborator in Ido-Wikipedia and also here, and I've noticed this error, but I cannot correct it, because the page is blocked from editing. I don't know if you are an administrator here, but need help from an administrator to remove the block and then to correct it.

Best regards,
