osc 2.3.3 can not modify customer details

[kaiman]

Hello.

 

I can not modify customers details through admin pane. When I click Update button, it's stuck on action=update and doesn't do anything else.

All I can do at that point is just click Cancel and nothing happend.

 

But i can delete customers.

 

Can anyboda help please?
