I downloaded SEO Utlimate Version 7.6.1 [http://wordpress.org/extend/plugins/seo-ultimate/] wordpress plugin for my blog site. I unzipped the downloaded file and uploaded the extracted folder to /wp-content/plugins/. When I activated the plugin from admin I got the following error:

Parse error: syntax error, unexpected T_IF in /home/xxx/public_html/wp-content/plugins/seo-ultimate/modules/author-links/author-links.php on line 1

I was using Filezilla to transfer my files. The “Transfer Type” setting was auto.

I changed the Filezilla transfer type to “Binary”

After change in the FTP settings I uploaded “seo-ultimate” folder again and tried to activate the plugin again. Wow it got activated.
