Hi there, I'm also having some issues after moving directories and tried several solutions from the codex but haven't been able to resolve.
I just posted this on another thread but maybe one of you gents can point me in the right direction?:
After trying to change the location of my site and following the directions step by step within the codex(http://codex.wordpress.org/Moving_WordPress), I seem to have made a mistake because and can't see the site anymore. The first time I had this problem I followed the 'Quick Fix Method' solution and was able to get back to the admin page...this time it doesn't seem to work~
I assuming the problem lies with the URL/URI information I put within the Administration > Settings > General being incorrect...
These are the links to the OLD url's which were working fine before I tried changing address:
This is what's supposed to be the home page link to the new address:
..and this is the message I get.
"Warning: require(./wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /home/halcyon/public_html/index.php on line 17"
..the thing is that file IS in the directory it says it's not. I can't figure out what's going on. Could someone PLEASE help me get my site back online! Would really appreciate it.
