One of the best way to increase the performance of a drupal website is by using caching. Caching is nothing but storing your data in such a way that whenever you want you get your data instantly. The fetching of data can either be your drupal code or by user when he visits the site.
We have a Drupal 6 site that has multiple blogs on it. We used to be able to create blog posts and have them auto tagged but now the autotagging seems to have stopped. I can see in the browser's URL bar that there is a directive to apply a taxonomy term '?edit[taxonomy][tags][18]=learning-through-diversity' whenever I click on the link to create a post. The problem is, it appears to not be working anymore. The term exists and if I manually add the term, it shows up fine in views.
I was trying to change the automated url setting so when new book page is create the /content is not used in the url, but admin/build/path/pathauto gives blank page with no logging errors?
