I very much resent any interruption to my work, Dr. Watson, but this case is certainly exceptional.

⚠ There seems to be an exception on the loose by the name of 'ErrorException'

Last seen around here: '/home/micky/readhead.pruebas.tel/App/Core/init.php'
On line 40

🧐 Could this be the reason?:

Undefined array key "HTTP_ACCEPT_LANGUAGE"

🔎 Follow these clues:

#0 /home/micky/readhead.pruebas.tel/App/Core/init.php(40): App\Core\Error::errorHandler(2, 'Undefined array...', '/home/micky/rea...', 40)
#1 /home/micky/readhead.pruebas.tel/public/index.php(2): include('/home/micky/rea...')
#2 {main}
