Forum: Fixing WordPress
In reply to: Slow posting and comments leading to timeoutAfter checking more… It’s probably not BackWPUp. http://wordpress.org/support/topic/backwpup-make-commenting-and-posting-timeout-on-my-server?replies=4
I could mitigate the problem somehow by changing the cache plugin, and running mysqltuner, but the thing that really did the trick was when Linode (my hosting provider) told me there was an hardware problem, and moved my site to another machine…
I got that kind of CPU usage before being moved to another serer: https://plus.google.com/110719562692786994119/posts/Ps95NH9tBrW

In reply to: [W3 Total Cache] Random Blank Pages – w3 total cacheMore a workaround, than a solution. I’ve written a script to delete cache files without <body>, and run it every 5 minutes in a cron job.
This is for another cache plugins, but it could be adapted to W3TC:

In reply to: [Quick Cache (Speed Without Compromise)] Random Blank PagesI can’t see anything in fpm-php5.log, but somebody noticed the problem appears to go away when switching from nginx to apache.

In reply to: [Quick Cache (Speed Without Compromise)] Random Blank PagesJust one more thing. That’s a ugly solution, but it works.

You just need to set WP_PATH to your WordPress installation path.I’ve setup a cron job to run it regularly on my VPS.

In reply to: [Quick Cache (Speed Without Compromise)] Random Blank PagesI’m still running Inove…

In reply to: [Quick Cache (Speed Without Compromise)] Random Blank PagesI’ve done some more checks
In cache directory
ls -l | wc -l
2382Nearly 2400 cached file.
grep -L body qc-c* | wc -l
23That’s 23 cached files without body. That’s just about 1% of the pages and posts, but still annoying. I guess I could write a script to delete cached files without body regularly, as a temporary hack. Would that cause problems with quick cache?
I checked one of the problematic pages.
Without body: http://pastebin.com/v1F8tGmX
After clearing the cache: http://pastebin.com/i0tHQmnmThe full header is generated in both files (until line 110), but there’s no body at all in the other, except a script probably added by cloudflare, and the </html> is also missing.
For W3TC, some people said it could be because it’s caching HTTP HEAD requests.

In reply to: [Quick Cache (Speed Without Compromise)] Random Blank PagesI’ve noticed the issue happens with WordPress posts, and visitors that get a cache version of the page, so I doubt there are sessions. I’ll paste a copy of the full and incomplete post source via pastebin.com, once it happens again.

In reply to: [W3 Total Cache] Random Blank Pages – w3 total cacheI’m now using another cache plugin (Quick Cache), and it has the exact same issue. I wonder what both plugins may have in common.
Still no notes, but based on CPU usage and TTBF, pages are now definitely cached. It did not work for about 2 to 3 days, with overloaded server, and 8s TTFB. Not sure why.

In reply to: [Quick Cache (Speed Without Compromise)] Quick Cache Not working with WPtouchA visitor also mentioned he got the mobile version of my website in Chrome browser in his desktop PC.
I’m using the free version of Quick Cache, so there are no options to configure the cache plugin to skip caching for specific user-agents. Is there another method to avoid this issue?
Forum: Plugins
In reply to: [Quick Cache (Speed Without Compromise)] Features Removed.The only problem I’ve found to be a serious issue for a free version is the caching of the RSS feeds that prevents a feed update, at least with feedburner. RSS is a feature that I’d assume most bloggers use to promote their site.
W3TC does not work for me reliably, and WP Super Cache broke my site in Firefox. Quick Cache works for me, with good performance, and no site effects for me yet, apart from the feed issue.

In reply to: [Quick Cache (Speed Without Compromise)] Update blocks my feed from updatingChanging the cache update time to a few minutes is probably a working solution, but not ideal.It seems to old option “URI exclusion patterns” is only available in the PRO version.
I’m trying to put “define(“QUICK_CACHE_ALLOWED”, false);” somewhere, but I can’t quite find the right place yet.

In reply to: [W3 Total Cache] Random Blank Pages – w3 total cacheThere’s this option in page cache settings that looks related:
“Reject HEAD requests: Disable caching of HEAD HTTP requests
If disabled, HEAD requests can often be cached resulting in “empty pages” being returned for subsequent requests for a URL.”Unfortunately it’s grayed out and unchecked for me, and blank pages happen often enough for readers to notify me a few times a week.
I also have had some timeout issue when posting and emptying spam recently, so I may have other issues as well.
Custom code area works fine for me, and display one ad at the bottom of all pages.
If you want to add ads at the top (under the blog title), and use the default theme, look for wptouch_advertising_top and place your code below.
No problem now. I’ll mark it as resolved, even though there might never not have been a problem directly related to BackWPUp.
