Fatal error: Call to undefined function file_scan_directory() in /drupaldir/includes/common.inc on line 2115

I disabled caching (Administer - Site Configuration - Performance - Caching mode: Disabled) and the problem went away. This is with version 5.7 using “Cache Mode: Normal”. I hadn’t seen this on earlier versions.

I don’t even recall what I was looking for but I came across Maruku which is a library that implements the Markdown syntax, the PHP Markdown Extra syntax, and its own meta-data syntax. It should fix problems with underscores in links. It seems like the Markdown with SmartyPants module for Drupal also uses PHP Markdown Extra in its version for Drupal 6.0. That should be nice should I upgrade at some point. But I will start using Maruku on my Rails apps now and see what happens.

There are at least 4 feeds I'd like to be importing into this site but cannot because they are Atom feeds which the Drupal Aggregator module does not support. So it looks like if I want to have that functionality I'll have to switch to another module.

Wanted to fix the site search today and found the problem was database permissions. To fix I just granted the necessary permissions. Of course, I could only do that because I have access to the root MySQL account. Other Drupal sites on shared web hosting accounts might have to come up with other solutions. I’ve listed a few of these below.

While I'm not sure of the value of page counts I tend to enable them in Drupal. To do so I set "Administration - Logs - Access log settings - Count content views" to "enabled".

While this is no means an exhaustive list it is a point of reference for what tags to consider allowing on a website that allows user contributions in html.

<a> <em> <strong> <cite> <code> <ul> <ol> <li> <dl> <dt> <dd> <h1> <h2> <h3> <h4> <h5> <h6> <b> <i> <tt> <big> <small> <ins> <del> <blockquote> <q> <img> <pre> <table> <tr> <th> <td> <p> <br>

These are modules that I’ve installed relatively quickly into new Drupal setups. They’re not always the best or needed but more often than not add useful functionality.

• http://drupal.org/project/adsense
• http://drupal.org/project/captcha
• http://drupal.org/project/globalredirect
• http://drupal.org/project/marksmarty
• http://drupal.org/project/pathauto
• http://drupal.org/project/token
• http://drupal.org/project/xmlsitemap (buggy but promising)

I did a lot of looking at 3 column Drupal themes and here’s what I liked:

• http://drupal.org/project/aurora
• http://drupal.org/project/bluebreeze
• http://drupal.org/project/cms-theme
• http://drupal.org/project/Pleroma
• http://drupal.org/project/relax
• http://drupal.org/project/sib
• http://drupal.org/project/ubiquity (fixed-width)

They all have issues that need tweaking but I found most of them a good place to start.

Both of these links give a nice screenshot and some useful descriptions of the themes:
