[Haskell-cafe] Edited page on HaskellWiki cannot be stored

I am trying to add an event to the events template on HaskellWiki; when pressing the "Save changes"-button, I get the message: Database error A database query error has occurred. This may indicate a bug in the software. [e0eb045a214da98ee73cb349] 2025-06-24 14:08:03: Fatal exception of type "Wikimedia\Rdbms\DBQueryError" Can anyone have a look at this? Henk-Jan van Tuyl
