dear all,

could you please advisd if anyone came across the same problem as mine?

after transfer my 1.38a site from one host to another, the website https://www.xxx.com works okay, but the admin has problem.
when typing https://www.xxx.com/admin, it is just a blank page.
when typing https://www.xxx.com/admin/login.php, and fill in username, password, click "login", then it is still a blank page.
but infact, i'm aready logged in.

also, after chages someting in the admin area, after clicking "save" button, it also gives the blank page. however it is saved succesfully.

does anyone know what it the problem?

To me, this looks like either something has gone astray when you transferred the files to the new site, OR the /admin/includes/configure.php file has been corrupted.

Oh, and you really need to upgrade ASAP
