cannot login after changing hosts

I doubt thats it,

I have to admit that I never have heard of any problems regarding wrong line endings causing such issues, but the evidence is striking. template_functions.php has 1296 lines; +1295 additional line endings = 2591. The message says that is caused by index.php line 179. 179-89=90, where GS calls header().

I suggest to double-check that PHP files have been uploaded as text files and not as binary files. Alternatively, removing the ?> in the second but last line of the respective files could also help.
