[WendyMin]

Is anybody here to help me or have the same issue? :(

[billyjacoby]

Im having this same issue too...

[saulable]

Yep, my syntax highlighting is gone too.

[robin-macpherson]

Same here, I've been having this issue for the past few weeks :(

[telmogoncalves]

Same here. Have anyone figured out what's wrong?

[telmogoncalves]

Alright, this is pretty stupid, but I've found out that it keeps working just by changing the grammar to Babel.

Hope it helps.

[SamSteele01]

@telmogoncalves Can you elaborate on what you did?

[telmogoncalves]

@SamSteele01 on Atom, what I did is changing the grammar to Babel. On the bottom bar, you should see displaying what grammar the file you've opened is using.

[telmogoncalves]

If you're on Mac you can try this:

1. ⌘ + ⇧ + P
2. Type "grammar"
3. Type "babel"
4. Enter

@telmogoncalves Thanks for the reply. I figured that out after posting here. I didn't like having to do it every time I opened a file. Did some digging... References this issue. The tl;dr is to uncheck tree-sitter parsing in core settings. For me I also had to move the 'themes' array into the 'core' object in config.cson. Like so:

// .atom/config.cson

core:
   ...
   themes: [
     "one-dark-ui"
     "babel-react-syntax"
   ]
