I think I just managed to crash the PHP on our server.
Known culprit: I update the search page and managed to forget a closing curly bracket on:
{exp:search:keywordsdid a search…..and nothing using PHP works anymore. All other stuff works OK. Static Pages (Apache), FTP, SSH all seem to be working OK. But any PHP script just stalls.
Any idea what the problem could be? (I did contact the server support, but that may take a while)
