[Resolved] 4.0.16-> 4.0.17 Broke my wordpress blog

[lugus]

Upgraded using cp to 4.0.17. When I went to login to my Wordpress blog it tried to download the file login.php rather than run it. Same with other admin php files. When I went back to 4.0.16 the problem went away.

Any ideas?

PHP 5.3.3 on Centos 5.x

looks a serious issue and hard to trace...

what's your wordpress version? I upgraded to 4.017 on a wpmu 2.9.2 site, php 5.3.2, without problem.

Version 3 of Wordpress. Is there a chance I need to rebuild php after the upgrade? Have you tinkered with php memory or anything along those lines?

[NiteWave]

4.0.17 select latest APC 3.1.4 instead of 3.1.3p1 when build PHP in admin console. so if you want to try APC 3.1.4, rebuild PHP in 4.0.17

I would if I thought it could help but I do not have APC compiled in my php at all and 4.0.16 works fine without it. Are you saying I have to have it now for 4.0.17?

[NiteWave]

do you have other opcode cache like eAccelerator, XCache enabled?
if none of them enabled, recommend you have one, absolutely it'll improve the php performance a lot.

opcode cache is built as php extension, you can save/keep your current php binary, just build out apc.so, xcache.so, eaccelerator.so. and enable one(and only one) in php.ini.

I do not have any opcode cache compiled at the moment while I experiment. I will when this server goes into full use. I definitely do not want to add it now until I sort out why patch 4.0.17 is breaking the php.

Also I have just found if I try and compile php under 4.0.17 I receive:

Fail to generate build script, please try to manually fix the error first.
Failed to create manual install script: /usr/local/lsws/phpbuild/buildphp_manual_run.sh

maybe a permission issue? please check

ls -ald /usr/local/lsws/phpbuild/
