+Because drupal frequently misbehaves, here is a list of useful snippets.
+This isn't intended for end-users of the distillery, but just listed here so we don't have to keep searching for it. 
+
+# Enable Stack Traces
+
+The DSOD usually only says `The website encountered an unexpected error. `
+When `Reports > Recent Log Messages` is inaccessible, you can enable full stack traces.
+
+Run `vim web/sites/default/settings.php` and add:
+
+```php
+$config["system.logging"]["error_level"] = "verbose";
+```
+
+Might have to ignore the readonly flag (with `:w!`).
+
+# Manually disabling a module
+
+When doing manual migrations or upgrades, an error like the following can occur
+
+```
+(Currently using Missing or invalid modules The following modules are marked as installed in the core.extension 
+configuration, but they are missing:
+```
+
+To fix this, either re-install the module (using composer and friends) or run this code to disable it:
+
+```php
+drush eval "\$modname='id-of-module';\$module_data = \Drupal::config('core.extension')->get('module'); unset(\$module_data[$modname]); \Drupal::configFactory()->getEditable('core.extension')->set('module', \$module_data)->save();"
+```
+
+# Factory SSH Forwarding
+
+To portforward all services you can use the following ssh command:
+
+```
+ssh -L 3306:sql:3306 -L 7200:triplestore:7200 -L 8080:phpmyadmin:80 -p 2222 slug@wisski.agfd.fau.de
+```
+
+This forwards:
+
+- [GraphDB on `localhost:7200`](http://localhost:7200)
+- [PhpMyAdmin on `localhost:8080`](http://localhost:8080/)
+
+You can also access raw sql, e.g.:
+
+```
+mysql --host=localhost --port=3306 --password --user=username
+```
+
+and load an sql file with `source [filename]`.
