Forum Blogs doesnt work after 4.0 upgrade and sitemap?
 

i have seen this error

Fatal error: Call to undefined function fetch_avatar_html() in /home/*****/public_html/includes/blog_functions_main.php on line 519

when i try to join my blog page.


and when i click rebuild sitemap it says:

The directory the sitemap files are to be written into is not writeable. Please change the permissions on the path to be writeable by the web server or enter a different path in the sitemap options.

Where is the sitemap file?


thanks
