Drupal 6.x

Transmit has the capability to change the permissions of a file as it uploads it to your server. Make sure the check-box "Auto-set my permissions" is unchecked. Typically, Drupal (all versions) like to have most of their files at octal 755 or 775. If you accidentally have Transmit set to change things to 644 or something similar, your newly-uploaded Drupal site will not work.

Certain patterns can be harmful or dangerous for your site.

Aliases that begin at the root

If you have an alias such as [title-raw] for a piece of content that users can create you allow them to create pages like "http://www.example.com/google1234567.html" that are used to authenticate Google or Yahoo! webmaster tools. This then allows the user to authenticate as the owner of the site and control the entries inside those tools (including removing your site from the index, changing between www and no-www versions of your site, telling the search bot to visit less frequently). This is not the default and is not recommended. If you want short aliases at a minimum make your pattern something like "c/[title-raw]" to put a character "c" before every title.

Index Aliases

For example, certain situations where you create a pattern like forum/[title] and you have "Create Index Aliases" turned on pathauto will then create a page at example.com/forum/ which over-rides the default example.com/forum page. In order to fix this problem you can clear out that entry from the url aliases either via the GUI at example.com/admin/path or via the database table. A better path to create would be forums/ or discussions/ so that the names don't collide.

Transliteration Problems

To manage date formats in Drupal 7, you need to manage both format types and formats themselves in the Regional and Language settings.

Drupal ships with a sitewide contact form since version 4.7 that you can use to allow site visitors to send feedback. As mentioned in the help text on the contact form settings page, you can also use the body area just above the form to give site visitors your postal address or share any other information.

However, because you can't specify an input format for the contact form page, the additional information you add will display without linebreaks or paragraph breaks and look pretty ugly.
