Hi,
till yesterday I was able to configure my wpmu installation, now something is broken. I'm not able to activate themes or change options.
When I try to activate a theme (Site Admin -> Themes) it shows up a 404 page on the url http://.../wp-admin/wpmu-edit.php?action=updatethemes , the log says Premature end of script headers: php5.cgi, referer: http://.../wp-admin/wpmu-themes.php
and in the wp-admin directory appears a nice core dump file
$ file core
core: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style, SVR4-style, from 'php5.cgi'
anyone can help me understand what is broken?
thanks
agnul
p.s. I'm on dreamhost hosting and using wpmu 1.2.5a (I also tryed to remove all plugins but this doesn't solve)
