I configure a couple of items as requestable, but when i go to requestable menu and click the button request, it bring me to an error page showing "Whoops, looks like something went wrong."
Please enable debugging so we can get a more useful error message.
Thanks for replying.
Not sure if i did enable it correctly. I do still getting "Whoops, looks like something went wrong." without further error after i enable it

If you're running this on Centos via install.sh, why are you editing the docker.env?
Thanks for the respond. Sorry for my bad understanding, i do not get what you are trying to say, can you elaborate further?

According to your screenshot, you're editing the docker.env file, but according to your bug report, you installed via install.sh, which doesn't use docker, so changing that file would have no effect.
Thank you for spending time explaining to me. These are the log that i get the log from laravel.log. Is that correct?

Looks like something is wrong with your email settings.
Thank you for your help. It is working now
