Migration issue: sidebars disappeared

Hi, I need urgent help. I set up webpage on temporary server and now moved to working server. But there is problem with migration using “Transfer Theme Options Data”. It looks like sidebars created with Sidebar generator disappeared. The issue is that sidebars are working on webpage but they are disappeared in admin panel – when I go Sidebar Generator in menu it looks like blank page (in place where should be sidebar list). Somebody may help me?
temporary server: http://cynlut2.bunkerstudio.pl/
working server: http://cynlut.pl
(both servers are placed on one machine and one ip so configuration are the same)
help plz
