I'm sorry for my english
I am lost, I searched everywhere, I can not find a solution.
By performing an OMV update, I lost the web interface display with 502 Bad Gateway - nginx.
And to know everything, I am now in version OMV 5.0.3-1.
I do not know how to go back.
I feel that he has updated me PHP7.3.
In short, help me please
