Chapter number on page header is not updated in LaTeX document

Question

I have a small technical problem but I have been unable to find a solution to it so far.

In my thesis document, the chapter numbers that are displayed on page headers are not updated. It keeps on showing "Chapter 1. Some_Chapter_Name" as header. The reason I don't understand is that the chapter numbers on the first page of each chapter is properly incremented but not as page headers for next pages.

Any help will be much appreciated. I am attaching the complete style code for my LaTeX document later on. I believe this is the relevant section to the problem:

=============== SHORTER VERSION =================

% Set up the document
\documentclass[a4paper, 11pt, oneside]{Thesis}  % Use the "Thesis" style, based on the ECS Thesis style by Steve Gunn

%% Chapter Heading ---------------
\renewcommand{\chaptermark}[1]{\btypeout{\thechapter\space #1}\markboth{\@chapapp\ \thechapter\ #1}{\@chapapp\ \thechapter\ #1}}

Answer 1

Your document is oneside, but Thesis.cls expects twoside. This can be seen in these two lines of Thesis.cls:

\lhead[\rm\thepage]{\fancyplain{}{\sl{\rightmark}}}
\rhead[\fancyplain{}{\sl{\leftmark}}]{\rm\thepage}

That class uses old-fashioned fancyheading commands. For twoside mode, the optional argument refers to even pages, the mandatory argument refers to odd pages. Here, in oneside mode, \rhead overwrites the right mark with the page number.

Solution:

Change to twoside mode or, if you would really like to use oneside: call \lhead and \rhead without optional arguments or use recent commands of fancyhdr.

Note: since you did not post a minimal working example, it took me a lot of time to work out the solution. I've done this because you don't know the importance of minimal working examples yet or don't know how to create them. Have a look at What is a minimal working example? and at I've just been told I have to write a minimal example, what is that?. Next time please provide a small compilable code example which shows the problem.
