When replying to a topic the composer does not automatically fill the title input field which creates an error when using lavender theme:

Thanks for the help

Hi, you might have a mismatched version of NodeBB core and Lavender/Vanilla. Can you post the result of git rev-parse HEAD for core, as well as your Lav/Vanilla versions please?
