Hi, I attempted to upgrade to 2.3.1 and received these two errors:
Warning: main(./wp-blog-header.php) [function.main]: failed to open stream: No such file or directory in /home/happybur/public_html/index.php on line 4
Fatal error: main() [function.require]: Failed opening required ‘./wp-blog-header.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/happybur/public_html/index.php on line 4
What do I do to resolve/fix?
Help please. Thank you!
