i have exactly the same problem… please someone help..
I figured out my problem. I was running WPTouch and for some reason, it wasn’t working properly with WP Super Cache (even though I had it set to work with it by populating the UA strings and ticking the proper box in the plugins box). After getting rid of WPTouch, it worked fine after I reset WP Super Cache to the default settings and re-applied my own settings.
I have the problem that the preloaded cache is always deleted.
And i get an email that the preloading was cancelled.
Is that what’s going on? Preload wipes all the cache each time it starts up?
I’ve suffered from slow and stalling reloads on a wordpress with less than 100 pages. The preload system seems so slow, and I figured it was my box.
However, I found that disabling garbage collection and disabling preload finally let me keep my cache files in place.
I run a nearly static website. I only blog about once a month or so. I don’t need updates any more often than I update the site!
So I’ve found that http://www.deadlinkchecker.com/ can crawl my site, check all links, and essentially preload the cache for me! And it’s very fast! Much faster than the preload system. Why is that!?
I should mention that cache files still seem to be wiped randomly, even though garbage collection is set to 0 and preload is set to 0 with all checkboxes removed.
What’s causing cache files to get wiped out?
Trent, do you have WPTouch installed? That’s what was causing problems for me.
I don’t have WPTouch and I agree with what TrentSterling has said. I have tried setting garbage collection to 0 and preload to 0 as well.
Still the preload cache gets wiped out.
I don’t have WP Touch. I’m also near vanilla at the moment. The worst part is that I can’t seem to track when the cache gets wiped. It takes me a day or two to see the numbers drop to 0.
I’ve been experimenting with everything off and on, uninstalling and re-installing the plugin. The only thing I haven’t tried is a fresh WP install.
Also, what does it mean when only the WP-Super-Cache is wiped, but the WP cache stays full? I’ve seen that happen too. The debugging log is a bit too verbose for me to figure it out on my own. It’s also really hard to replicate.
Time will tell.
EDIT: Ugh, there is an edit button!
Anyway, hosting is with GoDaddy, and I can post whatever stats you might consider useful.
The reason I mention GoDaddy is because I hear there’s a limit on the number of files you can have- and cache’d html would eat at that limit.
But looking in the cache folder, there’s only a few hundred files. I can’t imagine that’d be it.
I am on a dedicated server with unlimited file storage. I don’t think this is a GoDaddy issue. It must have something to do with the WP Super cache plugin settings or another plugin conflict?
I’ve been having a similar problem. My entire cache clears whenever i publish or update a post, or when a comment gets moved between folders (i.e. approved, or automatically moved as spam). I set the comments to logged in users only so that issue of automatic movement of spam comments went away nearly completely. The cache would clear every few minutes before I changed the comment setting because of the number of spam comments. Now it just wipes when I approve comments or change a post. Still not perfect, but at least now it is predictable for me, and far less frequent.
Can anyone else confirm/test that they are seeing something similar as to the cause of the cache being deleted?
jt70 thank you for posting this. I am looking for a plugin which will completely disable comments and pingbacks on all of my posts/pages/custom post types in order to test this assumption which appears plausible.
I haven’t noticed the cache clearing when I update posts but I have a lot of spam comments on Akismet.
Maraki, I went through the same thing–the trackbacks on old posts were getting me even though I turned it off. I can’t recall exactly what I did, but I think I found a script to run in my database to change the old posts to have them closed to trackbacks and pings. I don’t think I used a plugin.
Glad you aren’t having the problem with the posts too. I can’t figure out a workaround for it.
