Http Error 500 after uploading laravel app

https://laracasts.com/discuss/channels/laravel/upload-project-laravel See @Qlic There were many other post on this very same subject

@jlrdw , Thanks for taking time to reply. But actually I had the app working correctly when I first installed it few days back. I uploaded recent code to the site and it goes down. Tells that there is nothing like .htaccess & folder strucutres as some are suggesting. Error log says something missing . But I uploaded every single file how come it is working on local machine and not on server.

Need to backtrack and find out what you overewrote that made it not work.

I've working instance of the app at localhost. Uploaded everything using FileZilla and somehow it's missing something. No failed transfers in Filezilla also . Hope to fix the issue soon.

After uploading did you change your configuration to the production server rather than localhost double check that stuff it's easy to miss one.

Yes app environment & url updated accordingly in config/app.php

@jlrdw , Please read the error log

PHP Fatal error: Call to undefined function Illuminate\Support\value()

I think there is no issue with server configuration.

Look at that line 168 see if it gives you an idea I'm on mobile now not desktop.

Make sure you copied all the hidden files.

the chance of version compatibility is high.
