Hi, all. I installed STACK system, however Its found the following problem
Failed Could not start an instance of Maxima. 
It is not possible to use or edit STACK questions without a working connection to Maxima.
Monico,
Sorry about this difficulty - if you'd like to email me I'd be happy to help you fix this. It is probably a file permission issue.
The general installation instructions are online at our Wiki
http://stack.bham.ac.uk/wiki/index.php/Installation
and an FAQ section on is given for each platform under the category "Installation".
http://stack.bham.ac.uk/wiki/index.php/Category:Installation
If you manage to track down what wasn't working without any further help, please let me know by email and we will try to improve the install scripts.

hi,
I have encountered similar problem in stack test suit.
everything is working fine except Maxima Plots. After requesting plot
test several times (switching from alternate to standard and back) it
eventually works. I am not sure what this problem could be related to.
I have tested it on
Ubuntu 9.10 ( Karmic Koala), Maxima versions 5.17.1 and 5.18.1.
Maxima timed out
Problem connecting to the CAS. 
Please check your settings.
There should be two different plots. If two identical plots are seen then this is an error in naming the plot files. If no errors are returned, but a plot is not displayed then one of the following may help. (i) check read permissions on the tmp directory. (ii) change the options used by GNUPlot to create the plot. Some examples are given in maxima\maximaConfig.php around lines 50. Currently there is no web interface to these options.
If the no errors are returned, but you cannot see a plot above try the following steps:
P.S. Of course I have correct perms on tmp directory.
Hi Monico,
Did you find solution to this problem? I am facing same problem. My Ubuntu is
9.04. Maxima is by default 5.13.0 installed through aptitude. I am using Apache2 , MySql and Moodle 1.9.9
I installed STACK and configured with Maxima and Moodle. On running TestSuite
at the end of STACK istallation it shows connection error with Maxima using
command "maxima". Otherwise I am able to start Maxima.
