Hi all,

I installed flaskbb but redis cannot be set for the hosting company (pythonanywhere) but that's ok, so I disabled it in the .cfg.

REDIS_ENABLED = False

REDIS_URL = ""
REDIS_DATABASE = 0


# Celery
# ------------------------------
CELERY_BROKER_URL = ""
CELERY_RESULT_BACKEND = ""

However, I have the following error while trying to register:

Is it somehow using default config properties? I do call the app with the correct cfg.

from flaskbb import create_app
flaskbb = create_app("/path/to/myconfig.cfg")

(By the way, I call flaskbb alongside my main app, which is my main website in which I want to include a forum.
I use:

app.wsgi_app = DispatcherMiddleware(app.wsgi_app, {"/forum": flaskbb})

Is it the right way to do it?)

Thanks for your help!

Best,

OK, the code does seem to look for the correct .cfg (is the name/path is not correct it returns an error) but ignores what is inside.

I ended up calling flaskbb this way:

from flaskbb import create_app as create_flaskbb
from flaskbb.configs.default import DefaultConfig as Config

Config.REDIS_ENABLED = True
flaskbb = create_flaskbb(Config)

app.wsgi_app = DispatcherMiddleware(app.wsgi_app, {"/forum": flaskbb})

It does work better, no error most of the time.

But still, sometimes (rarely but still) I got the same error as before, when, for some reason, it decided to use Redis after all...
