Checklist

• [X] The issue exists after disabling all extensions
• [ ] The issue exists on a clean installation of webui
• [ ] The issue is caused by an extension, but I believe it is caused by a bug in the webui
• [X] The issue exists in the current version of the webui
• [X] The issue has not been reported before recently
• [ ] The issue has been reported before but has not been fixed yet

What happened?

If I use any kind of LORA it will give "TypeError: 'NoneType' object is not iterable" error.

Steps to reproduce the problem

1. Go Txt2img and add LORA to your prompt.
2. Hit generate.

What should have happened?

It should have been work as expected

What browsers do you use to access the UI ?

Additional information

I have updated the reForge and Nvidia Gpu driver.

[KamCastle]

Experiencing the same after updating.

[Panchovix]

Okay reverted the changes related to that, will try to implement it via another way when I can.

Should be fixed now.

@Panchovix Thanks. It works now.
