Same problem here, occurred after installing W3 Total Cache, using disk caching.

Front End Website and W3 Total Cache are functioning properly, but Admin login is causing error below, which results in display of the WordPress 404 page (not actually a 404 error)
Site is hosted on a CentOS 5 Cpanel server.

/usr/bin/php: symbol lookup error: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so: undefined symbol: zend_atol, referer: https://mywebsitehere.tld/wp-login.php
 Premature end of script headers: index.php, referer: https://mywebsitehere.tld/wp-login.php

Requires WordPress Version: 2.8 or higher
Compatible up to: 3.1
Last Updated: 2010-9-6

Compatible with 3.1? or 3.0.1?

I’m still working on a couple of test sites on a couple of different hosts to try and get this working…

• template fallback/failover issues in IE with woothemes/delegate on a Virtualmin CentOS site using APC OpCode
• /wp-admin 404 issues on a Cpanel CentOS site using disk caching

Thanks braddor, I’ve since switched to APC for my server and all is running well.

Frederick, APC is working better than xcache. Thanks for this plugin!

in /etc/php.d/xcache.ini

change these to something like:
xcache.var_size = 32M
xcache.var_count = 3
xcache.var_slots = 8K

save; restart httpd

c3m, Yes Xcache is fully functional only if you run PHP as apache. I haven’t found a way to get w3tc’s admin tasks (empty cache) to work running FCGID, that’s why I’m running minify via disk. I have xcache-admin setup properly and can access the admin, but w3tc’s login prompt does not work — on my server xcache requires https to log into the xcache admin; perhaps if I can modify the plugin to run the empty requests as https, it will work.

I do run other sites on my server as apache with mod_php, however the tradeoffs in convenience and security are not worth it with WordPress, IMO — having to change permissions on upload directories for auto-updates and installs is a hassle.

I’m thinking of removing Xcache and installing APC instead, since it will likely be better supported.

Nonetheless, I am very impressed by the performance gains and ease of use with this plugin. Here’s hoping switching to APC will solve my admin issues and allow me to cache more in memory vs disk.

Xcache is obviously now supported, but I thought I’d add some info. I have found that in my environment (Virtualmin on CentOS with Xcache, PHP running as user in FCGID), what works best is to use Xcache for the database and object cache, and disk for the minify and page cache.

This is because Xcache does not really support much administration (flush) except when running mod_php as user apache. I burned a lot of time trying to get it to work to run xcache for all caches, which is very very fast, but the need to constantly flush the page and minify caches was difficult, especially when lots of admin area users are involved.

You won’t see the FCGID processes in the Xcache admin pages, but believe me the database and object stuff does get cached although it does not show up. I have similar experience with Joomla in the same environment and xcache does indeed cache the db queries and objects.

It’s not possible because the way the slider works is by forming a series of divs that have incremental “left” style attribute… think of a series of divs, side by side. The slide javascript works by dynamically changing the “left” style attribute of the div which encloses the other divs which hold your posts’ content excerpt and thumbnail.

Try looking at the code in Firefox with Firebug installed and you can see what’s up, even see the style attribute change dynamically.

I have several installs of wordpress on 2 different servers.

Both have cURL installed and curl test scripts work properly.

Both are shared hosting platforms (cpanel and virtualmin) with virtual hosts running PHP as user under fCGId.

php -m shows curl running as a php module

Auto-embed is enabled in Settings > media

I have cleared caches, turned off wp-cache or super cache, restarted apache after 2.9 upgrades, etc. to eliminate those as issues.

When I paste in a valid, embeddable Youtube or Vimeo URL, and save the post, the URL is saved as plain text and no auto-embed occurs.

I’ve installed 3.0.2 and I am having the same issue: visual editor does not appear. It briefly appears, but then disappears… same issue with either Firefox or Safari on Mac.

I have all of my plugin folders permissioned and owned properly.

I find it cleaner and simpler to have a separate CSS for each category via a functions.php in the themes directory.
e.g.

function cat1style_css() {
if (is_category('1')) {?>
<link rel="stylesheet" type="text/css" href="<?php echo bloginfo('stylesheet_directory') ?>/cat1.css" /> <?php }
}
add_action('wp_head', 'cat1style_css');

function cat2style_css() {
if (is_category('2')) {?>
<link rel="stylesheet" type="text/css" href="<?php echo bloginfo('stylesheet_directory') ?>/cat2.css" /> <?php }
}
add_action('wp_head', 'cat2style_css');

With this technique you can achieve a true cascade if you order the category functions properly. You may name the stylesheets and functions whatever you wish, for even more simplicity. (is_category variables should be numeric according to the cat#.)

I eventually got all of my sites updated to 2.5… but it seemed to work better on the ones where I waited until 2.5.1. Everyone is loving the new features once they get used to the radically different admin and wysiwyg interfaces. I am totally enthralled with the plugin update system… but I do worry that the greater dependence on centralized system could become a vulnerability.

We’ve also added cFormsII plugin for event registration, and it has seriously added to the number of folks who are coming to our events… I think it gives them the impetus to register and commit, and then the follow-up communication seals the deal.

Hey, sorry for the long delay, I wish this forum had a “subscribe” feature so I’d know when a thread I’ve posted gets some comments.

To answer some questions, the theme was based on the Upsilon theme from LivingOS – https://themes.livingos.com/ I added quite a few modifications to make it work with sidebar plugins and integrate the flash slideshow.

The blank green bar on some pages is OK because it only shows links if the page has subpages. maybe I need to rethink that and have it collapse if there are no subpage links.

I’m thinking of doing a redesign of the homepage to make it less bloggy and get rid of some of the sidebar stuff that’s not needed. Plus I’d like to widen the template a bit.

We are loving WordPress with EventCalendar 3.1.1rc — it’s great for churches and non-profits and small businesses. Configured correctly, it’s a serious search traffic magnet.

Sorry, I thought this miscellaneous forum category was for across-the-yard questions and discussions… plus I think the BGP block issue may apply to the growing interconnectedness of the WordPress platform (see revised post above.)
