I found in .vscode folder a file settings.json

{
“vetur.validation.template”: false,
“eslint.validate”: [“javascript”, “javascriptreact”, “typescript”, “vue”],
“vetur.experimental.templateInterpolationService”: true (change this to false. It worked for me)
}

I didn’t understand why that folder is there. All my other projects don’t have that folder

Thank you @metalsadman. It worked perfect. You helped me a lot, like allways.
All your answers in previous Topics were very helpful.
I was in doubt about if I should make a post just to confirm that the answers worked and thank the people who answered. There are foruns where these kind of messages are not allowed due to big amount of messages.
Thank you again. VueJs and Quasar are great tools. I hope in the near future I also can help others that are starting with VueJs and Quasar.
