SD-webUI not generate pic

[janco1999]

Hi , I was install SD-webUI v1.7 under windows 11, pic generate without problem.
Because of some training reason , I need the v1.6 for testing and verification.

in the same system, I just get clone [SD-webUI v1.6 link] and modify the webui-user.bat same as v1.7 which I used before.
webUI can be launched without problem, but I cannot generate any pic from v1.6, it seems no any respond in system.
Any one has idea can help me? thank you !
