Error: An error occurred while attempting to connect to your weblog: Invalid Server Response – The response to the blogger.getUsersBlogs method received from the weblog server was invalid. You must correct this error before proceeding. or Invalid response document returned from XmlRpc server
Other:
Invalid response document returned from XmlRpc server

Possible solution Solution : find the class.IXR.php file (under wp-includes), edit the file, and look for function output($xml) FInd the line that calculates the length $length = strlen($xml); and replace it by $length = strlen($xml)+3;

or if modsecurity is enabled set the following in an .htaccess file <files xmlrpc.php>SecFilterInheritance Off </files>

wordpress support simple and plan 

Don’t copy and paste text from MS Word because it adds junky code that IE hates. Either remove the bad mso code, or repaste your text from a text editor like notepad.

also
Instead of using crtl-v to past into the blog, plus use the “paste from word” button under the editor within WordPress. The button is next to the easer button.

or past into notepad2 and then into wordpress

Fatal error: Allowed memory size of 33554432 bytes

Fix:
locate the wp-settings.php file
Search for define(’WP_MEMORY_LIMIT’, ‘32M’);
Change 32M to 64M : define(’WP_MEMORY_LIMIT’, ‘64M’);

for some reason this is different from setting the memory limit in the php.ini file. . :(

Ensure you have a .htaccess file with the following

# BEGIN WordPress
<#IfModule mod_rewrite.c#> *take out the #’s*
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
<#/IfModule#> *take out the #’s *

# END WordPress

Unable to create directory – Is its parent directory writable by the server

fix
chmod -R 777 wp-content/uploads

do not chmod wp-content to 777 , only chmod the uploads folders and subfolders.
