Troubleshooting

Installation issues

• Check the version of Python
• Check the version of Web2Py that was used for the Sahana release you downloaded
• Check the permissions of the web2py and Sahana application files
• Check models/000_config.py connection string to see that it is either sqllite or a valid mysql connection on your machine

Update issues

• Check the database connection settings in models/000_config.py
• Clear the /sessions directory - Lingering sessions on your browser can cause issues after an update
• Clear the /databases directory
• Drop and Create the database if mysql
• Restart Web2Py
• Check the version of Web2Py that was used for the source branch that you merged from

IOError: [Errno 13] Permission denied

This happens with cygwin patch on Win32.

Solution is to copy the file on filesystem to another name, then delete original & rename back.
