Could you please confirm if you encountered this issue with the previous version too or it just started happening with 4.2.2? Looking forward to your reply so we can investigate this in more detail! All the best, Yes, definitely after 4.2.2 since this morning. First Solution for me now: comment the row. //$notices = Notices::getInstance(); Testing: After comment, again WordPress is running After erase comment, WordPress is running too My conclusion, the error only comes one times, first call the website, but with hard break Thank you for letting us know about this, we will continue investigating this on our end! Waiting for new Version, using this $notices inside the function This reply was modified 1 day, 6 hours ago by meinService . Hello @meinservice , Since this error only appeared for you upon activation of the new version, we need the full error, including the stack trace, to understand what is going on. Do you still have it in your logs? The $notices is just an init for the NoticeController class, and normally, it should not affect anything or generate an error. Sorry, in dont have logs of what happens, only the white Screen and DIE – Message. But after that, the error again dont appears
