Bugs can behave as application crashes or as misbehavior. You are welcome to collect info on any such issue and submit it to the issue tracker.
Turning on debug mode will make the exceptions show in the browser. This is useful to debug issues in the web interface, but not suitable for production environment as it has performance consequences and might leak private data.
Weblate can produce detailed logs of what is going in the background. In
the default configuration it uses syslog and that makes the log appear either in
/var/log/syslog (depending on your syslog
The Celery process (see Background tasks using Celery) usually produces own logs as well. The
example system-wide setups log to several files under
Docker containers log to their output (as usual in the Docker world), so
you can look at the logs using

Analyzing application crashes¶
In case the application crashes, it is useful to collect as much info about the crash as possible. The easiest way to achieve this is by using third-party services which can collect such info automatically. You can find info on how to set this up in Collecting error reports.
Lots of tasks are offloaded to Celery for background processing. Failures are not shown in the user interface, but appear in the Celery logs. Configuring Collecting error reports helps you to notice such failures easier.
In case Weblate performs badly in some situation, please collect the relevant logs showing the issue, and anything that might help figuring out where the code might be improved.
In case some requests take too long without any indication, you might want to install dogslow <https://pypi.org/project/dogslow/> along with Collecting error reports and get pinpointed and detailed tracebacks in the error collection tool.
