Troubleshooting Guide

So this document was created to highlight all the common errors with VAOS that you may find if you either installed it incorrectly, or just some things of note if you do something incorrectly.

Please not that this guide is not a catch all, hence why I am teaching you how to read the log files you see up front. So, when you do ask for support, we can get to solving your problem quicker. Our time is very valuable so less time diagnosing the problem, more time working on new features.

Log Files

There's two log files you need to know about. One is for Laravel (the framework that runs VAOS) and the second is your web server log.

Laravel.log is located in /VAOS/storage/logs/

Web server logs depend on your hosting:

• error_log (Shared Hosting) located in /public_html (relative to your index.php file)

If it's not in the above directory, consult your hosting company.

Dedicated Hosting is as follows:

• error.log for nginx located in /var/log/nginx/
• error.log for apache2 located in /var/log/apache2/

APP_DEBUG=true

A feature in Laravel used a lot in testing is outputting the error directly to the webpage. This takes the place of the Whoops, Something Went Wrong generic 500 server error. While this is great for development, it's ill advised to use in production.

To enable this feature, in your .env file, simply set APP_DEBUG=true if it's currently false.

Reading the stack.

So you got the error log files located. You're probably wondering now what the hell you're looking at. So when looking at a log entry, there's a few key components.

• The Timestamp
• The Error Itself
• The Stack Trace

Here's a full one for an example (with some directory redactions)
