here's my info
Site:
www.clmitchell.net
Host Provider: Bluehost.com
Server Info:
Linux: b/L8
Apache: 2.2.14
PHP: 5.2.11
MySQL: 5.1.43-log
Joomla: 1.5.17
I tested on my Fedora 12 Laptop with the following config with no problem (the one difference being that on the test env i didnt set "Site Offline" to Yes (slapping forhead).
Linux: 2.6.32.11-99.fc12.x86_64
Apache 2.2.14
PHP : 5.3.2
MySQL : 5.1.45
Found this in the PHP error log:
[30-Apr-2010 18:05:48] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/uploadprogress.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/uploadprogress.so: cannot open shared object file: No such file or directory in Unknown on line 0
This error seems to have been generated by replacing my 1.5.15 .htaccess with the one that came in 1.5.17:
[Fri Apr 30 18:05:56 2010] [warn] RewriteCond: NoCase option for non-regex pattern '-f' is not supported and will be ignored.
Bluehost has more stringent permissions requirements than my test server (or the upgrade archive for 1.5.17)...once i corrected this everything was back up and running!
