check the condition inside the loop for attachments.
if( !has_post_thumbnail( $post_id ) ) { }
But the Query will retrieve all relative results unnecessarily and filter inside the loop.we can use this if your query is more specific to the expected results.

Do you have FTP details? if yes, try using them on filezilla and if works fine, then use this at admin section. It may work:)

1.Turn off all plugins and try upload.
2.Look the functions.php, if you write any code to change roles& capabilities of users.If yes turn off and check.
3.check the upload folder permission 644 or 777
4.If no luck turn on the debug mode and you may get some more info about the issue.

1.Check your htaccess and make sure you use right ‘Base url’
2.I guess this will work when you permalink with ID(www.domain.com/?p=23) not with post name (www.domain.com/about). If yes then check permalink section and turn on with post name and replace default option.
3.Sometimes permalink will not work if you use ‘/%post name%/’ remove ‘/’ at the End.

That must be server configuration issue, try checking the FTP details,user permission or file permission.and final option is contact server support.

Ideally wordpress gives the error message like ‘Error establishing database connection’, when database not configured properly. So try checking DB credentials once again.
Also check your Hosting (localhost at most cases) if it has hosted at different server.

@jmeyer2485, Yes u can change the logo with some small css tweaks.

I have added the site title also, but notification email has still “from” address as the “From WordPress” ? Is there any other setting?
