   - Switch to LiteSpeed and try a ruby/python app
+===== Troubleshooting =====
+If your application does not work properly, you can try two simple steps to check if the application has been setup properly:
+  - If possible, switch back to Apache temporarily to verify if the application works properly under Apache.
+  - Check if any error has been logged into ''<APP_ROOT_DIR>/stderr.log''. If it has, fix the error and try again.
+For example:
+A Python application writes an error to stderr.log under the application root directory, ''/home/user1/dingodossier/mbntp/stderr.log'':
+<code>
+Traceback (most recent call last):
+  File "/home/user1/dingodossier/mbntp/passenger_wsgi.py", line 8, in <module>
+    wsgi = imp.load_source('wsgi', 'mbntp/wsgi.py')
+  File "/home/user1/virtualenv/dingodossier_mbntp/3.4/lib64/python3.4/imp.py", line 171, in load_source
+    module = methods.load()
+  File "<frozen importlib._bootstrap>", line 1220, in load
+  File "<frozen importlib._bootstrap>", line 1200, in _load_unlocked

+  File "mbntp/wsgi.py", line 10, in <module>
+    from django.core.wsgi import get_wsgi_application
+ImportError: No module named 'django'
+</code>
+This indicates Django was not properly set up for the application.
