Hi,
im not sure if its a bug or just a failure in the installation process/file missing etc. Sometimes when i open the blog i get the message:
Call to undefined function: serendipity_mb() in .../blog/serendipity/include/functions.inc.php on line 68
and no blog is there :(
Im using Serendipity 0.8.3 ...
