Hi,
We have several silverstripe sites running on a mac server. One of them has suddenly disappeared, showing only a blank page, (polar research.otago.ac.nz) the rest of them are just fine (e.g. biochem.otago.ac.nz).
Error logs say "Fatal error: require_once(Zend/Log.php): failed to open stream: No such file or directory "… etc
We can't find a Zend directory but we can't find it in any of the other sites that work just fine either.
If you try rebuilding the site you get "The requested URL /polarresearch/index.php/dev/build was not found on this server"
We are at a loss as to how to troubleshoot this - my local version is working fine. No one has done anything to the site at all. The only changes to the server have been one MySQL database added, and one of the other sites has had a wee facelift by adding another set of theme files.
Any help would be appreciated, thanks in advance
