Function/class/method coloring in PHP is wrong

[Tuuuukka]

Just updated the Catppuccin theme for nvim and I noted that the functions in PHP are now colored white. In other languages they are blue as they used to be (I'm using Frappé). I tried overriding the color with custom_highlights but it made no difference in PHP, only in other languages.

I haven't installed any new plugins, LSP's etc. in the meantime. Anyone else having this issue? I also have Treesitter in use, but disabling it made no difference.

I'll answer myself, might be beneficial for someone else too:

The issue was with Treesitter after all. I couldn't update the tree-sitter-php for some reason. Running TSInstall all and TSUpdate solved the issue. Don't know what it was hung up on.
