I have migrated my wordpress website from my desktop over to siteground for hosting. Prior to doing this I had been using free hosting at x10. The first time I transferred the site everything worked fine. The second time I tried (new version of the website) I found that every page except the home page had a 404 error (this was with x10). I then got hosting at siteground and am still having the exact same problem. Any solutions to this?
My .htaccess file
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /testsite/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /testsite/index.php [L]
</IfModule>
# END WordPress
