[Oblique] Logo Size Excerpt Lenght not working after move to a new server/URL

Dear all, yesterday I moved my wordpress website with Oblique theme from http://www.myname.it/test to http://www.newname.it, I also updated the HTACCESS file and the website is now working at 98%

there are 2 functions that are not working:
1) in Theme -> Configuration -> Header -> Logo Size / the input field to setup the max width for the logo is not working, I can’t type any value

2) in Theme -> Configuration -> Blog Options -> Excerpt length the same problem as above, the input field to setup the max lenght is available but it’s not possible to type any value inside

Please, how can I fix this issue?
thanks a lot for your support
