CENOCRE  This software is an utter piece of crap and shows how Apple has forgotten it's roots of making good logical software. It looks okay - at first.

The layout is illogical with no rational reason for a tab being at the bottom left, then a tab for a sub-section being at the top center and then the buttons doing the same function can appear in totally different places in similar windows. There is simply no rational order to the design and totally defies the Human Interface guidelines that Apple itself created.

Much worse however are the incredible bugs that have been there for years that can take an entire server down. Duplicate a web site and you may actually end up working on another site than the one intended. The software seems to randomly switch from site to site without notice for no apparent reason so you may end up with screwed up httpd.conf files.

Additionally, when you copy and paste the software can add a space to the pasted item. Spaces in Apache configuration can also take down a server!!! This shows two bugs, the addition of the space to begin with and the lack of detection of the space when saving the configuration.

Given that even a minor configuration error in something such a log file can take down a server (that is Apache's idiocy) and Apple's software introduces errors this can be very dangerous software keeping a web server going.

For web serving stay away from Apple's Server and go with something such as Abyss Web Server from Aprelium and CrushFTP or PureFTP.
