The current main logo in [[ https://el.wikiversity.org/wiki/%CE%9A%CF%8D%CF%81%CE%B9%CE%B1_%CE%A3%CE%B5%CE%BB%CE%AF%CE%B4%CE%B1 | el.wikiversity.org ]] (top left) is missing the fourth letter from the end (Η). The correct wording is Βικιεπιστ**ή**μιο (in lower case) or ΒΙΚΙΕΠΙΣΤ**Η**ΜΙΟ (in upper case), as is used throughout the main page's text, rather than ΒΙΚΙΕΠΙΣ**ΤΜ**ΙΟ as it appears in the currently used logo. This is clearly a typo, [[ https://el.wikiversity.org/wiki/%CE%A3%CF%85%CE%B6%CE%AE%CF%84%CE%B7%CF%83%CE%B7:%CE%9A%CF%8D%CF%81%CE%B9%CE%B1_%CE%A3%CE%B5%CE%BB%CE%AF%CE%B4%CE%B1#Spelling_of_word_%CE%92%CE%B9%CE%BA%CE%B9%CE%B5%CF%80%CE%B9%CF%83%CF%84%CE%AE%CE%BC%CE%B9%CE%BF | which has been pointed out (twice) since 2017 ]]. The correct logo [[ https://commons.wikimedia.org/wiki/File:Wikiversity_logo_2017_el.svg | is available on Wikimedia Commons ]], but isn't used. An administrator must configure the use of the correct logo.
