Warning: call_user_func_array() [function.call-user-func-array]:

What version of this theme are you using?

I tried this theme (1.9.3.9) on a local WAMP installation (WP 3.7.1) and found no errors.

Have you at any point of time modified this theme’s files? Switch to the Twenty Thirteen theme, delete this theme and install it again and see if it solves the problem.

If nothing works edit the functions.php file of this theme and comment or remove the following line

require( $template_directory . '/core/includes/version.php' );

This is only a temporary fix.

Hay Jesin, thanks a million. The temporary fix provided by you has worked.
This is an older version of the theme (1.5.9)
There is no Child Theme created for this theme, and at this stage I am not in a position to update as it will change the look of the site.
Will work on it when time permits.
This is another great reason to use a child theme ??
Thanks Again.

Nice to hear that your problem is solved but 1.5.9 released way back in 06/07/2012 and so many things have changed since then.

I suggest you use a tool like quickdiff.com to find the differences between your theme and the original one and move those to a child theme ASAP.

Else somewhere down the line a WordPress or a plugin update might break the entire site because WordPress might remove deprecated functions in future releases.

Yes Jesin, I am aware of that.
I use Child Themes for all my WP setups, but this was done way back by someone else. The WP version was 2.7 and I updated it to 3.7.1 and also the plugins to their latest version, and this error popped up.
My initial conclusion was that some plugin after update has caused this, so i disabled all plugins but the error remained.
As i had not much time to fix this, I posted it on the forum and gladly you helped me out.
