——— I am having the same problem. I found this thread and followed these
instructions and it worked. However, I needed to put my old index.html page back
for a while whilst I made some adjustments.
* I repeated the process when I was ready to swap back again….moved the old index.
html and renamed my index.php (it was a copy) but now I’m getting a different
message in the Response tab:
* Warning: require(./wordpress/wp-blog-header.php) [function.require]: failed
to open stream: No such file or directory in /home/content/43/10338043/html/
index.php on line 17
* Fatal error: require() [function.require]: Failed opening required ‘./
wordpress/wp-blog-header.php’ (include_path=’.:/usr/local/php5_3/lib/php’) in
/home/content/43/10338043/html/index.php on line 17
* Any ideas?
