I activated WP-CACHE. started receiving the following errors (below).

I attempted DE-activated Wp-Cache and it blew out all of my plugins (deactivated everything) and I am still getting the following error messages.

Please – how can I clean this up?

Did you remove the reference to wp-cache from your WP-config file?

Thanks for the response.

This is the only line in the config file:

define(‘WP_CACHE’, true); //Added by WP-Cache Manager

Yes, you’ll want to remove that if you want to deactivate WP-Cache altogether. Change it to this:

//define(‘WP_CACHE’, true); //Added by WP-Cache Manager

Thanks again. I’m back in.

However, the blog is slow – I’d really like to use WP-Cache but it crashes every time.

I’ve tried it on two different instances of WP and three differen themes. Crash & Burn.

Any ideas?

Are you running any other plugins? There may be a conflict of some sort. I’ve found WP-Cache to be temperamental myself, I don’t use it. I believe WordPress has built in caching now, so WP-Cache is really only necessary for very large sites. If your site is slow, it may be a server issue. WordPress has been very fast for me on every host I’ve ever run it (at least 4-5 different hosts now), so I’d try to figure that out instead of trying to fix it with a plugin.

Hope that helps!

wp-cache hangs up on my site when the expired pages equals cached pages. Some people are suggesting WP Super Cache might resolve some issues.

This is great information. I was beginning to think I was the only one having problems with this plig-in.

Glad WP now has a self cache service 😀

If WP 2.3.1 has caching embedded do I need or will I see any improvment by using WP Super Cache?

Probably. Depends on how much traffic you’re currently getting. If it’s just a little, I’d stick with the object cache in 2.3.1 since you may wind up with more time being spent on static page generating that may make it not worth it. If you get a fair amount of traffic, try the super cache and see if things improve.

Thanks, Just launched and not all that much traffic. I”ll keep this in mind, in case this thing takes off.

Hey,

I’m finding the same or similar problem. I just found this post, and made the change, which only seems to be two “//” forward slashes at the beginning of

//define(‘WP_CACHE’, true); //Added by WP-Cache Manager

However, I get this problem now:

//define(‘WP_CACHE’, true); //Added by WP-Cache Manager
Warning: Cannot modify header information – headers already sent by (output started at [mydomain]/blog/wp-config.php:2) in [mydomain]/blog/wp-includes/pluggable.php on line 770

Here is the post where I’m trying to figure this out:
