WP Super Cache Expired Pages Not Deleting

This problem was reported before and is supposedly fixed in the latest version. As far as I know this has nothing to do with 2.7. If you have the latest version, we’ll have to get Donncha’s attention ??

I just tried, it works fine with me, contrary to a previous version.

I’m showing I have 0.8.6

Weird. I guess we’ll have to wait until Donncha is online then…

Not to rush anyone but do we know when to expect a response? I see that he provides awesome support for this plugin but I’d just like to know what to expect if anyone has a clue. The site isn’t updating for some people for a week now. I try to deactivate the plugin and then other people can’t see the site at all. As I’m logged in, I can continue to see the site in my browser with all the updates. It is the same if I only turn it half-on. Is there some way to manually remove the 364 expired pages through ftp without messing something up? I just need a work around. Since traffic is low for us around the holidays, I’m ok with not having the plugin activated at all if I can get the site to work without it.

Check for files or directories with backslashes in them (\) in the supercache directory.

Check your cache/.htaccess file. The admin page of the plugin lists the rules that should go into this file. It’s NOT the htdocs/.htaccess file.

Unless your site is extremely busy, the half on mode should be fine.

I don’t see any files with \ in them.

Following is my cache/.htaccess file

# BEGIN supercache
<IfModule mod_mime.c>
AddEncoding gzip .gz
AddType text/html .gz
</IfModule>
<IfModule mod_deflate.c>
SetEnvIfNoCase Request_URI \.gz$ no-gzip
</IfModule>
<IfModule mod_headers.c>
Header set Cache-Control ‘max-age=300, must-revalidate’
</IfModule>
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/html A300
</IfModule>

# END supercache

We’ve had up to 10K visits in an hour before it shut the server down.

I found some info in the error logs that may help.

bennettaj – that’s useful. That error on line 227 is a bug, but it’s part of a chunk of code that means that the plugin couldn’t write the supercache file. Not sure why though.

Hello donncha,

I’ve started using super cache few days ago and actually I was very satisfied by its results. I downloaded the latest version and installed it on wordpress.

I am using PHP Speady plugin, and am not sure if it conflicts with super cache, or prevents cached pages from being deleted. Anyway, whenever I leave my blog for a day of such, I come back to find it full of weird characters. Nothing shows up in the blog; only a white page with those characters.

So what I do to solve that is that I delete the cached files and turn super cache plugin off.

Do you have any idea y this is happening?
Thank you.

I finally removed all files under supercache and then it started working ok. I’m good now.

aouni-tahech – the plugin doesn’t work with php-speedy. There is a patch that works for some people but I haven’t tested it so I can’t vouch for it. Look at the php-speedy website for more info.
