We recently completed a project that needed to have a rather robust tool for dynamically creating and saving reports as PDF files. We’ve done similar things in the past but always wrestled with the dynamic pdf creation tool we were using. We decided to look around at what other tools people were recommending and settled on using ABCpdf from webSupergoo.

Installing it on the server was a breeze, our developers had an easier time getting things working, files sizes were about 10% smaller, and load times seemed slightly faster than our previous tool.

When we upgraded from 2.5.1 to 2.6 links to the individual posts started throwing 404 errors. After a little digging around we found this fix on wordpress.org:

If you need/want the index.php to be there, then on the Settings->Permalinks screen, add some values in for the category and tag bases. The words “category” and “tag” will do just fine. As long as they are not blank, this should work around the bug.

I hope this helps some other people out there who were gnashing their teeth like I was 5 minutes ago.
