# Troubleshooting

## Introduction

This page provides troubleshooting steps you can perform when content is not loading properly.

## Delete Bin/Obj

By default, Gum projects copy content to the bin folder if the content is newer in source. If a file somehow becomes newer (such as by copy/pate, or reverting) in the bin folder, then the source fill will not get copied over.

You can delete bin/obj folders and re-build your project to verify that content is loading correctly. Alternatively you can try loading the .gumx file that is in the bin folder to see if it visually matches the content in source.

## Clearing Browser Cache (Web)

On web targets (KNI BlazorGL and other WebAssembly hosts), the browser may serve a cached copy of your `.gumx` project and its files. If your content looks out of date even though the source has changed, the browser cache is a likely culprit. Performing a hard refresh or clearing the browser cache makes sure you are loading the current `.gumx` file rather than a stale cached version.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flatredball.com/gum/code/files-and-fonts/troubleshooting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
