If you host your site at 1and1 and

a) encounter wordpress or its admin panel crashing down while or after activating or working with QTranslate or

NextGen Gallery plugin

or

b) find Nextgen Gallery not creating thumbnails or having problems with uploads

you may find this helpful:

1. Open .htaccess file in your root folder

2. Add these lines:

Options All -Indexes

AddType x-mapp-php5 .php

AddHandler x-mapp-php5 .php

3. Save and hopefully see it work
