Possibly related, https://www.mediawiki.org/wiki/Help:Magic_words/es is currently outputting [W0PdugpAAD4AACjgbZ8AAAAF] 2018-07-09 22:12:12: Fatal exception of type "Exception" - However, I cannot see any obvious problems in that page's translation history or content: https://www.mediawiki.org/w/index.php?title=Help:Magic_words/es&action=history and https://www.mediawiki.org/w/index.php?title=Special:Translate&group=page-Help%3AMagic+words&action=page&filter=&language=es
I did try a purge, with no change.
I did Not try to "mark page ready for translation", because I don't have time to go through the extensive changes in the root page's content and also fix the markup. HTH.
