I have created a fresh install of Pressbooks on my Mac mini M1 running Monterey 12.4 using MAMP as a local web server. Everything seems to work OK but this error message is displayed on the top of the press books page.
Warning : The magic method Pressbooks\Book::__wakeup() must have public visibility in /Applications/MAMP/htdocs/wordpress/wp-content/plugins/pressbooks/inc/class-book.php on line 62
I’m not sure if this is related to MAMP or Pressbooks. Has anybody else come across this ? Suggestion for a solution?
