    Hi there!

    We’d like to have the Local Graphviz installation using the dot Graphviz binary, and with our path (online server) we receive an output with Permission denied.

    Please, could you let us know how to proceed?

    Thanks!

    I need more information to be able to help:

    * How did you install GraphViz?
    * Where is it installed? What is the full path and filename for “dot”? Have you tried running it manually at the command line using that path?
    * Does the server run something like SElinux or AppArmor and are they set to restrict program execution by the HTTP server?

    Thanks Chris!

    Sure, we installed GraphViz in WordPress.com, the online server. The error appears before including the command in a page, when it’s updating the settings of the plugin.

    The path is /srv/htdocs/

    I do not think it will work on that sort of service. The plugin “TFO-GraphViz” requires the separate program GraphViz to be installed on the server, or the PHP module of the same.

    I have looked at a pure JavaScript implementation, that would run in the browser and thus not have these server dependencies, but it is a fair amount of work. There are other plugins that do this, though I have found them a little short on functionality personally.

    Unless you can arrange to have the GraphViz dependencies made available on your server I doubt you will be able to make use of TFO-GraphViz on it. It is a limitation of that kind of hosting service.

    We’ll try to install a separated program. Yes, this hosting shows some limitations, let’s try to solve it!
