error Livewire is not defined

Hello, i've installed Akaunting on my hosting, run the setup, everything seems to work. But in the console, in many pages i have the error "Uncaught ReferenceError: Livewire is not defined", could someone help me? i found over the internet that it could be a setting in config/livewire.php, they say to change 'asset_url' => 'public', i tried but with no success.
any suggestions? thank you

update:
from this discussion:
https://akaunting.com/forum/discussion/installation-update/cant-get-the-setup-wizard-and-unable-to-login

i solved changing in the .env file the app_url entry, it was www.mysite/subfolder/index.php,
like suggested from Melda Karaoğlu i solved changing to www.mysite/subfolder

now the error about livewire seems to be fixed, but i have an error when i try to send an invoice over email, ithe page displays the server error, and in the console i have a 500 error, it tries to load the page:

https://mysite/subfolder/index.php/1/sales/invoices/1/email

and obviously it throws the 500 error

have you got some suggestions?
thank you
