What system requirements does serendipity have?
You need a PHP installation together with a MySQL or PostgreSQL server. We also require you use the Apache webserver, because we utilize a number of internal functions to make Serendipity run correctly. To fully enjoy serendipity, you should have either ImageMagick’s convert binary installed on your server or a PHP installation with gd2 support (recommended). You should also verify, that your Apache takes notice of the “.htaccess” file in your document root (Override All), otherwise s9y won’t be able to run properly.
