Dear Teammates,

Using MW 1.26.2 on Windows 2008, I am having the below problem from the GraphViz Talk \
page which also has a solution pertaining to wshellexec (see below).  So I don't \
understand the solution which was:  "Problem apparently solved. It was the same as \
one of the messages above, and it was solved the same - copying wshellexec from \
1.22.15 over the current version".

If you understand it, please let me know.  I couldn't find a file named wshellexec in \
MediaWiki. tx,
L
Graph is created then \
deleted[edit<https://www.mediawiki.org/w/index.php?title=Extension_talk:GraphViz&action=edit&section=21>]


Hello.

I'm using mediawiki in a windows 7 environment, with an Apache server at localhost.

GraphViz is fully configured and running, but the image graph is created and then \
deleted, showing nothing on screen. I've reproduced the exact command shown on log \
("<program files>\Graphviz2.38\bin\dot.exe" -T "png" -o "<wiki \
directory>\images\graphviz\images\Example_digraph_G_dot.png" "<wiki \
directory>\images\graphviz\Example_digraph_G.src") and in fact does create the image, \
but the folder is empty after refreshing the page (even if I manually put a copy of \
the intended image there). Where can be the error? Why the data is gone? tx,
L
