# Trouble shooting ## Empty datetime object Couldn't render template "index.html: undef error - Can't call method "strftime" without a package or object reference at /var/www/fixmystreet.127.0.0.1.xip.io/fixmystreet/perllib/Utils.pm line 232 - You might have a problem with a datefield that has been left empty by one cobrand that another expects to have a value. Inspert the problem table in the database. - You may have problems being returned by memcached that your database does not have. Restart memcached to rule this out. ## Wrong cobrand is displaying - Make sure that your hostname does not contain anything that another cobrand is matching on. For example if your config is ``` yaml ALLOWED_COBRANDS: - fixmystreet - zurich ```` Then a domain like `zurich.fixmystreet.com` will match `fixmystreet` first and that is the cobrand that will be served. ## Account creation emails not arriving Your receiving email servers may be rejecting them because: * your VM IP address has been blacklisted * your ISP blocks outgoing connections to port 25 (mobile broadband providers often do this) * sender verification has failed (applies to `@mysociety.org` servers) - check that your `DO_NOT_REPLY_EMAIL` conf setting passes sender verification (using your own email address works well). Perhaps check the entries in `/var/log/mail.log` to check that the message has been sent by the app, and if it has been possible to send them on. ## Translations not being used The locale needs to be installed too or the translations will not be used. Use `locale -a` to list them all and ensure the one your translation uses is in the list. ## Database connection errors trying to run update-schema Make sure that you specify a database host and password in `general.yml`. You may need to explicitly give your user a password.
