No spammer at al and definitely not competition.
It destroyed my website, period.
I was able to solve it myself. But the plugin should be doing what I did.
This is what I did:
Made an .htaccess and added this:
# BEGIN WordPress
RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L]
# END WordPress
This can be a small problem but nothing of my site was working anymore.
If this occures, the pluging should notice this and should rise an event that there is no (writeable) .htaccess file.
Kind regards
Bob
P.S.: I agree with Jan!
