I am using the template from Elena Botoeva to create an A0 poster. How do I change the background to just a colour gradient, i have tried changing the style file but can't get it to work.

Set your desired colors in \setbackgrounddarkcolor, and \setbackgroundlightcolor. In the following exampls I used

\setbackgrounddarkcolor{cyan!70!black}% ORIGINAL: colorone!70!black
\setbackgroundlightcolor{orange!70!black}% ORIGINAL: colorone!70!

The complete code (introducing the above colors in fancytikzposter.tex):

    Macro for creating a block node:
    \begin{itemize}
    \item[] \textbackslash blocknode\{Block Title\}\{Block Content\}
    \end{itemize}
    Macro \textbackslash blocknode has three parameters. The first one is
    optional and it is the position of the block. The first block will be
    automatically placed to (\$(firstrow)-(xshift)-(yshift)\$), which is the
    left corner below the title block. In most of the templates, (firstrow) is
    set to (title.south), where \emph{title} is the alias for the title
    block. Each subsequent block is automatically placed to
    [(\$(box.south)-(yshift)\$)], i.e., below the previous block aliased
    \emph{box}.  You can also use an explicit parameter, e.g., $(-10,30)$ (note
    that (0,0) is the center of the poster). The second parameter is the title
    of the block. Finally, the last parameter is the  actual content. 
  }




  %% by default, the position of the new block node is right below the previous
  %% block node, stored in (currenty)
  %% box is the alias of the previous block, so we can refer to its boundaries

  %%%%%%%%%% ------------------------------------------ %%%%%%%%%%
  \blocknode{Making Title}%
  {To make title, use the standard commands \textbackslash title and
    \textbackslash author in the preamble, and then the following macro:
    \begin{itemize}
    \item[] \textbackslash titleblock\{50\}\{1.5\}
    \end{itemize}
    Macro \textbackslash titleblock has three parameters. The first one is
    optional and it specifies the shift of the title block w.r.t.\ its default
    position, which is set to (\$0.5*(0,\textbackslash
    paperheight)-(0,\textbackslash margin)\$). The second parameter is the width
    of the title block, and the third parameter is the scaling ratio (to make
    the title bigger or smaller).\\

    \small
    The syntax for specifying authors is similar to the one in aaai.sty.  Author
    information can be set in various styles: For several authors from the same
    institution:
    \begin{itemize}\item[] 
      \textbackslash author\{Author 1 \textbackslash and ... \textbackslash and
      Author n \textbackslash\textbackslash\\ 
      Address line \textbackslash\textbackslash           ... \textbackslash\textbackslash \ Address line\}
    \end{itemize}

    If the names do not fit well on one line use
    \begin{itemize}\item[] 
      \textbackslash author\{Author 1 \textbackslash\textbackslash           \{\textbackslash bf Author 2\} \textbackslash\textbackslash           ... \textbackslash\textbackslash           \{\textbackslash bf Author n\} \textbackslash\textbackslash\\
      Address line \textbackslash\textbackslash           ... \textbackslash\textbackslash \ Address line\}
    \end{itemize}

    For authors from different institutions: 
    \begin{itemize}\item[] 
      \textbackslash author\{Author 1 \textbackslash\textbackslash \ Address
      line \textbackslash\textbackslash \ ... \textbackslash\textbackslash           Address line \\ \textbackslash And ... \textbackslash And \\
      Author n \textbackslash\textbackslash \ Address line
      \textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
      line\}
    \end{itemize}

    To start a separate ``row'' of authors use \textbackslash AND, as in
    \begin{itemize}\item[] 
      \textbackslash author\{Author 1 \textbackslash\textbackslash \ Address line
      \textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
      line \textbackslash AND\\ Author 2 \textbackslash\textbackslash \ Address line
      \textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
      line \textbackslash And\\ Author 3 \textbackslash\textbackslash \ Address line
      \textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
      line\}
    \end{itemize}
    (though, I must say \textbackslash and ... \textbackslash and did not work for
    me with more than 2 authors, so just use commas where you need if it does
    not work for you either).
  }

  \blocknodew[($(currenty)-(3.5,0)$)]{30}{Variable Width Block Nodes} %
  { You can also create blocks of arbitrary width
    \begin{itemize}
    \item[] \textbackslash blocknodew[coordinate]\{Block width\}\{Block Title\}%
      \{Block Content\}
    \end{itemize} 
    % 
    In this case it is better to specify coordinate manually if you want to have
    blocks aligned vertically. \\

    Note that (xshift) and (yshift) are coordinates created in macro
    \textbackslash initializesizeandshifts, and they allow to have relative
    positioning of block nodes in an automatic fashion. If you want to define
    your own shifts, set new values for (xshift) and (yshift) using commands
    \textbackslash setxshift and \textbackslash setyshift.\\

    Also, it might be useful to know the y-coordinate of the south border of the
    previous block. You can retrieve it by using the command
    \begin{itemize}
    \item[] \textbackslash getcurrentrow\{box\} or \textbackslash getcurrentrow\{note\}
    \end{itemize}
    This coordinate will be stored in (currentrow), which can be used to
    specify the location of the next block node.

    If the number of columns is 2, then the last command will not have
    effect. \\

    You can also start a new column with an arbitrary x-coordinate by specifying
    explicitly the coordinate of the new block node as follows:

To suppresss the background decoration, you can redefine \BackgroundPicture before the lines

\ClearShipoutPicture
\AddToShipoutPicture{\BackgroundPicture}

A possible redefinition, producing only a shaded background would be:

\renewcommand\BackgroundPicture{%
\begin{tikzpicture}[overlay]
\shade[top color=backgrounddarkcolor,bottom color=backgroundlightcolor,] 
  (current page.north west) rectangle (current page.south east);
