Download Hotaru CMS 1.5.2 (RC1)

I am getting this error in admin area, I might be missed something, but let me know.

Code:

Could not find admin_theme_index_top function for widgets


Warning: Cannot modify header information - headers already sent by (output started at  ...../libs/Messages.php:52) in ...../content/admin_themes/admin_default/admin_header.php on line 30 

Adding users in admin area is working, but that settings in admin area is same "error saving settings"

 

yeah, that solved the problem, will be testing tomorrow, but I am ok and upgrading my site. let me know if you need anything to test.
