Attribute error

[KillerRu]

Stupid question but I keep bumping into this error when loading this extension.
I am totally new in the Stable Diffusion environment.

ERROR: 'StableDiffusionPipeline' object has no attribute 'cond_stage_model'

Please report this issue here. Make sure to provide the full stacktrace:
Traceback (most recent call last):

AttributeError: 'StableDiffusionPipeline' object has no attribute 'cond_stage_model'

I presume it's something simple... But can't figure it out.
I've tried a complete remove and reinstall of the extension but didn't show any result.
