docusaurus: Sidebar title and doc title don't change after updating it in file.

Is this a bug report?

Yes

Have you read the Contributing Guidelines on issues?

Yes

Environment

Docusaurus v1.3.0 NPM v6.1.0 Node v8.11.3 Macbook Pro with MacOs High Sierra

Steps to Reproduce

Tried to reproduce it in a fresh Docusaurus project, but can’t reproduce it there. What I can say about my own project is that it already has a lot of markdown files. I also have all of them in subdirectories inside the docs folder, so I also refer to them via their relative path in my sidebars.json file.

1. Have the dev server running
2. Have an existing docs file with its relative path in sidebars.json
3. Change the title of the doc file
4. Restart dev server

When building the project it also updates fine.

Expected Behavior

I expected the title to change to the new one in the sidebar and in the h1 header. This does not happen.

Actual Behavior

Title in sidebar doesn’t change and the h1 header doesn’t change, which used to work before, but sudddenly stopped working.

Sometimes I see this error in the console:

uhoh. Got error write EPIPE

But most of the time it doesn’t show up.

I also asked this in the Discord channel and got a workaround:

• Remove the i18n folder
• Run npm run write-translations
• Start dev server
• Everything updates like normal

Reproducible Demo

Could not reproduce it in a fresh docusaurus project and can’t share my own project here. If more details are needed I can provide them.
