Filesystem.php - failed to open stream: No such file or directory once moved to production

Assuming that file got copied over, are you storing anything in local storage? If you are, it may be that filesystems.php referneces the storag_path()...this may need to be looked at.

No, not that i know of. It's a simple expenses management app that doesn't even have a file upload form.

Where/what can i check regarding storage paths?

Here's an update.

If i just copy/paste my localhost installation without changing any of the configuration files - i get the login screen but i obviously can't login since the database settings are incorrect. So i swapped the .env file and managed to log in. But the second i revisit the same location twice - i get the same error which then crashes the whole application. here's a full error stack:

Are you copying vendor? Is there any reason your not doing composer install?

Can you login by ssh to this server?

I copied eveything. Like I said - there are several laravel apps already on that same shared hosting working perfectly (v5.2).

I can't do composer install on the server because it's a shared server - not dedicated. But again, all of my other projects work perfectly, and I deployed all of them the same way I did this one.

I'm really clueless about this since it works on my dev machine, and all the files are there.

Sigh... I recopied the exact same files again - and now i'm getting a slightly different error stack (still about filesystem though)

Same problem over here. Shared hosting, multiple Laravel installation.

One is 5.2 laravel and no problems.

Two on 5.3 and there are problems with Filesystem keeps on missing. I upload the Filesystem and back in ~5-7 days it delets it self.

Anyone allready found a solution?

Ask your hosting to modify the AV scanner. That turnes out to be trhe problem in my case. Server security settings kept deleting the file
