Okay team, so I figured this out.

First off on my set up the apc.ini file resides in the conf.d directory deep inside my /etc/php5/cli directory. I have know idea why it’s there, but this is the place. Anyhow, because I installed php_apc as a module (apt-get install php_apc) it uses the predefined apc compiled in settings which is why I was seeing the variables in dump out when I ran php -i. Okay to override any of these variables I just needed to add them to this almost blank file and it worked! Great!

As far as how to enable apc.php. This file is bundled with https://pecl.php.net/package/APC so don’t make the same mistake I did and try to keep accessing the /wp-content/plugins/w3-total-cache/pub/apc.php via your browser because that is not the same file and will not work. Anyhow, just upload the apc.php from the APC Package and your ready to rock. You should be able to view it from https://www.yoursite.com/apc.php

That’s about it for now.

By the way the /etc/php5/cli/conf.d/apc.ini is basically empty.

All it saids is
extension=apc.so

Thanks,

Please help

No problem. WordPress is amazing.

Also I recommend working on a Mac a Linux environment at the very least. Which will be helpful. Most Web Developers and Server Admins do so it will make it easier for you to get help if you get stuck.

I hope it’s not too late to elaborate on this question. But what is the benefit of “W3TC Compatibility Mode” and do most people use it? I’m trying to decied if I need to enable it on my site.

Floyd

It’s not the plug in. From my understanding if has to do with APC (Alternative PHP Cacheing).

I did read about a fix for it some time ago (something about changing some params in the the apc.ini file), but it didn’t work for me. Anyhow, the errors just fill up my logs and as far as I can tell don’t affect the site all that much.

I’ve also recently discovered this link this morning.

What this means is that the plugin can’t find your .htaccess file. This is usually in the root of your WordPress install and is needed by Word Press to create nice URL links.

Just log into your Terminal App (I have no idea what this is called on a PC) and create the file. Make sure to give is proper read and write permissions for your web server.

Philip

Just log into your Terminal App (I’m not sure what this is called on a PC) on your Mac and run that command just like you see above

ln -s /home/jazzguit/public_html/impacband.org/wp-content/plugins/wp-cache/wp-cache-phase1.php /home/jazzguit/public_html/impacband.org/wp-content/advanced-cache.php in your server.

This will create a symbolic link to the advanced-cache.php in your system.

Philip

I’ve had the same issue for months as well. I’ve had no luck resolving it. How about yourself?

Floyd

So what would be the script I want to use, to view what the cache is doing then? Is there another place I should be looking?

Philip

No problem. I wasn’t going to move anything. BTW I’m
Using W3 Total Cache not Super Cache. Does this have any bearing?

Hey alloyking,

I’ve discovered that there is are two apc.ini on my web server. One in the w3c-total-cache dir and one in my php5 dir. As far as I can tell I’m using (i think) the one in the plugins directory.

Anyhow, thanks for the feedback.

I’ve also discovered the apc.php in the pub dir of the plugin but can’t seem to get it to load in my stock WordPress install. I’m not sure why but I keep getting “unauthorized user” when I try to bring up the page. Any ideas?

Actuall, now that I look at it. It appears to be hitting the page, but I don’t pass the required test.

So I get this “Unauthorized access.”

$command = W3_Request::get_string('command');
$nonce = W3_Request::get_string('nonce');
$uri = $_SERVER['REQUEST_URI'];
if (wp_hash($uri) == $nonce) {

Any help?

It has been working for us, except for the thumbnail issue, which seems not to be a problem for us anymore. At least on my end.

I’m not using Jetpack but I’m using the W3TC and CDN.
