Forgive me if I come across as a little dim here, I am no expert when it comes to this but hoping someone can provide some guidance.
I have a shared hosting site that I have uploaded the contents of the latest development zip file to from Github but I keep getting errors in getting it to load, I cannot access a single page. I did get to a point where it was telling me there was an issue accessing the autoload.php file in vendor (see attached image) but I am not sure how to rectify this.
To test if it was an issue with the way the webserver was serving files, I created a seperate folder in the web root and uploaded the V3.0.2 downloaded from here: https://www.invoiceninja.com/self-host/9/. I then extracted this and went to /public/setup and it worked straight out of the box.
Because this is on shared hosting, I have no access to composer, the sites-available page or terminal. Could someone please give me some guidance on what I am missing when it comes to the development version? I need to use the development version as I want to try out the tickets function etc.
Any help or guidance would be greatly appreciated.
