I am having an issue with the firsthead option in scrlttr2 class. See attached code. The document compiles with firsthead=off but when the option is set to firsthead=on, it generates the following error message.
Head of first page ! Missing number, treated as zero.
I do not know if it is a compatibility issue or something else. This has happened with many tex files I use. Surprisingly enough the same tex file compiles fine on my work laptop.
My code is as follows:
\documentclass[
pagenumber = off, % Removes page numbers from page 2 onwards
parskip = half, % Separates paragraphs with some whitespace, use parskip=full for more space or comment out to return to default
fromalign = right, % Aligns the from address to the right
foldmarks=on, % Prints small fold marks on the left of the page
addrfield=on, % Set to false to hide the addressee section - you will then want to adjust the height of the body of the letter on the page by adding the following in this section: \makeatletter \@setplength{refvpos}{\useplength{toaddrvpos}} \makeatletter
fromphone = on, % add phone
fromemail = on, % add emaill
frommobilephone = on, % add mobile phone
firstfoot = off, % if first foot is on
firsthead = on
]{scrlttr2}

\parindentis already 0 afterparskip=half. And the result of setting\parskipto0.1\baselineskiplooks more like a printing error than intent. However, if you want to use such settings, you should use\setparsizes(see the KOMA-Script manual for more information). And I would recommend to change\raggedsignatureonly once (and after loading the LCO). – Schweinebacke Dec 13 '17 at 6:51
