I am currently creating a new style for an existing xf board. Frequently, it happens that I cannot save the template anymore because of a Syntax Error in the first line where xf syntax occurs. However, I haven't changed anything in this line and it worked well before.
It usually helped to export and import the style again, and I was able to make the same changes and to save them, but not this time. Does anyone have an idea to make it work again, or something I could check?
