\flushmaketitle not defined

Question

I'm really sorry to ask this question but I find myself unable to answer it for myself, with little idea of what went wrong:

I created a template for my CV using LaTeX, which worked fine for a year, but I let it untouched for 2 months. I had to recently upgrade my linux distribution and lost a number of libraries in the process (I mention it without a clue whether it's relevant or not). The end of the story is that now, I can't compile my .tex code.

Among various warnings, I see the error:

! LaTeX Error: \flushmaketitle undefined.

See the LaTeX manual or LaTeX Companion for explanation. Type H for immediate help. ...

                                               l.24               

\renewcommand*{\flushmaketitle}

Another maybe relevant warning is

LaTeX Warning: You have requested package moderncvheadiii', but the package providesmoderncvheadiii'.

LaTeX Warning: You have requested package moderncvbodyiii', but the package providesmoderncvbodyiii'.

Here is a cleared version of the .tex file:

Answer 1

Well, in the new version 2.0 of moderncv there was a renaming from old version flushmaketitle to flushmakeheaddetails.

That means you can try to change the error causing command \renewcommand to \newcommand (because the following command has to be defined new now) like

% <=====================================================================
\newcommand*{\flushmaketitle}{%  new version 2.0 flushmaketitle -> flushmakeheaddetails

That compiles for me, but I do not know what you expect and it could be there are other errors now. Please check that with the following MWE:

I changed the image file name too and get then the result:

Is that close to that what you need? If not the only chance is to install the old version of moderncv or change your code to be able to use verion 2.0 (that would be better in my eyes ...)
