Centering equations in classicthesis package

[Olumide]

I'd appreciate help in getting equations to be centered on the line in
the classicthesis package. For example, both of the following
equations aligned to the left hand side of the page:

\begin{equation}
x(t) = \sum_{k = 0}^{\infty} \alpha_k \phi_k(t)
\end{equation}

\[
x(t) = \sum_{k = 0}^{\infty} \alpha_k \phi_k(t)
\]

Thanks,

Please post a [url=http://www.minimalbeispiel.de/mini-en.html]minimal
working example (MWE)[/url] showing the undesired behaviour. I ask you
for this MWE since the following code works OK for me:

\documentclass{scrbook}
\usepackage{classicthesis}
\usepackage{amsmath}

\begin{document}

text text text text text text text text text text text text text text
text text text text text text text text text text text text text

\begin{equation}
x(t) = \sum_{k = 0}^{\infty} \alpha_k \phi_k(t)
\end{equation}
\[
x(t) = \sum_{k = 0}^{\infty} \alpha_k \phi_k(t)
\]

text text text text text text text text text text text text text text
text text text text text text text text text text text text text

\end{document}

Now that I think about it, perhaps you are using the fleqn option for
amsmath? Check if this line appears in your preamble:

\usepackage[fleqn]{amsmath}

if so, delete the fleqn option.

Thanks. The problem was caused by \usepackage{classicthesis-ldpkg}.

[Olumide]

To be specific, and for posterity, the problem was caused by the
directive: \RequirePackage[fleqn]{amsmath}

From the manual:
fleqn - position equations at a fixed indent from the left margin
rather than centered in the text column.

One other issue:

I'd appreciate some guidance on changing the equation Math font (in
the classicthesis package). I don't like the look of the Euler math
fonts. I've tried doing: \SetMathAlphabet{\mathnormal}{normal}{T1}
{cmfib}{m}{n}, but it doesn't work.

Thanks.

According to the classicthesis documentation, the dafault math font is
Palatino and you can use the eulermath package option to load the
Euler fonts for math.
