The 1&1 DynamicSiteCreator does not meet the latest technical requirements: it uses outdated technology called Flash which may cause security vulnerabilities on your website. In addition, the media reports the end of Flash is near and that some browsers, such as Mozilla Firefox, could permanently block Flash.
Therefore it is possible that some parts of your website will not display correctly. The 1&1 DynamicSiteCreator will be deactivated at the end of this year. After deactivation, your site will always be accessible, however it will lose its editing functionality.
Instead, the 1&1 WebsiteBuilder will be made available to you free of charge. With this new website building tool, you will have the means to recreate your website.
Below you can find detailed instructions on how to migrate your site orignailly built with the 1&1 DynamicSiteCreator over to the 1&1 WebsiteBuilder.
Some elements can be copied directly from your 1&1 DynamicSiteCreator website to your 1&1 WebsiteBuilder project, however others may not be as simple. Please refer to 1&1 WebsiteBuilder section of the 1&1 Help Center for assistance in recreating your website.
After you have completed the steps mentioned above, your site will be online!
