Questions[dekiwiki](server)

This is a new install of the Mindtouch Core on Ubuntu 10.04. I've been following the Installation Guide on the Mindtouch community site.

When I try to start the dekiwiki service, it crashes with the following error:

** (/var/www/dekiwiki/bin/mindtouch.host.exe:14465): WARNING **: The following assembly referenced from /var/www/dekiwiki/bin/mindtouch.core.dll could not be loaded:

I've double-checked and I've got Mono 2.10 installed and the System.Web.Routing assembly is definitely there, Mindtouch just isn't finding it.

Any ideas?

Anyone got Dekiwiki / Mindtouch running with fcgid-module? I get 504 and 500 all the time.

 mod_fcgid: can't apply process slot for /var/www/html/dekiwiki/index.php

I'm currently fiddling with SuExec and fast-cgi wrapper directory permissions, because I also employ a chrooted SFTP jail. Sometimes the first line about the process slot does not appear now.

I found a solution in german and will work it through now.

I am currently testing a new Mindtouch installation on a Debian web server.

When using the Math-extension (a extension which uses LaTeX to convert mathematical formulas into .png images and shows them on the web-page), I simply receive no output from the math extension (not even an error message).

I was digging deeper into the problem, I noticed that the following HTML code is send from the server to the client where the image of the formula should be:

<img src="local://7c81b24bae6310e118b6b59b095eff15/deki/services/default/17/images/07adeb54-461a-d4c1-f66a-a69d14e29c2f.png" />

I have no idea what the problem could be here, since there are also no indications of any errors in the access, error or deki-api log. The error is also not reproducible on my local system with the same configuration steps done.

EDIT:

As advised, I searched through the mindtouch forums, and woha, here is the solution: http://forums.developer.mindtouch.com/showthread.php?t=8112&highlight=math+local
