Technical implementation or system administration questions would be off topic on Web Applications.
We are a site for users of web applications, not developers, administrators or moderators.
If you want to migrate such questions anywhere then you might want to consider:
- Webmasters for questions where you are hosting things on servers run by others.
- Wordpress if the question is specifically about managing a Wordpress installation.
- Drupal if the question is specifically about managing a Drupal installation.
- Joomla if the question is specifically about managing a Joomla installation.
There are other sites for specific CMSes that I can't remember.
