My web server's power outage occurred and then my webpage doesn't work anymore. I'm using Plone ver 4.3.3 and Zope.
I found there is no problem at apache2 so i think the problem is at the plone. So I tried to restart plone and there was the problem.
I typed bin/instance fg but i got error message like this.
Traceback (most recent call last):
File "/home/kwlee/Plone/zinstance/parts/instance/bin/interpreter", line 265, in

ZConfig.ConfigurationError: There was a problem starting a server of type "HTTPServer". This may mean that your user does not have permission to bind to the port which the server is trying to use or the port may already be in use by another application. (Permission denied)
So i searched if there is another Plone running, so i did bin/instance stop and started again, but that couldn't solve my problem.
And i did ps aux | grep python and the result was like this.
kwlee 2974 0.0 0.0 17164 964 pts/14 S+ 16:38 0:00 grep --color=auto python
(kwlee is my account name)
How can i solve this problem?
