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[edithttps://www.mediawiki.org/w/index.php?title=Extension_talk:GraphViz&action=edit§ion=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
