**Note:** If you have a `CallbackQueryHandler` in your `ConversationHandler`, you will see a warning `If 'per_message=True/False', …`. It is a *warning*, not an error. If you're sure that you set `per_message` to the correct value, you can just ignore it.
### How can I disable these warnings though
They are generated with the [warnings](https://docs.python.org/3/library/warnings.html) module, so we can disable them using the module as well. For this example, we will use the [filterwarnings](https://docs.python.org/3/library/warnings.html#warnings.filterwarnings) method. So in your code, before you initiate the `ConversationHandler`, do the following:
```python
from warnings import filterwarnings
from telegram.warnings import PTBUserWarning
filterwarnings(action="ignore", message=r".*CallbackQueryHandler", category=PTBUserWarning)
```
Depending on your use case, you might have to change the message, but all other warnings shouldn't be raised without a reason, don't say we didn't do our best to warn you.
### Can I check, if a `ConversationHandler` is currently active for a user?
There is no built-in way to do that. You can however easily set a flag as e.g. `context.user_data['in_conversation'] = True` in your `entry_points`s and set it to `False` before returning `ConversationHandler.END`.
