W3 Total Cache
Blank Page & APC (8 posts)

    Hi,

    I have just installed APC 3.1.10 on our vps. When activating APC for the Page cache however then I just receive a blank page on my site once I hit a 2nd refresh. All the other caches are OK with using APC, but the page cache keeps producing this error. When I empty the opcode cache then briefly the blank page does not appear, but after 2 refreshes I'm receiving it again.

    Hope you have an idea what the issue at hand could be.

  2. Have you checked your error logs? Also set WP_DEBUG to true to see the errors on the blank page.

    Hi,

    Where can I check the errors logs? I tried looking in wp-content/w3tc/log and /pgcache but both directories are empty. I had turned on the debug mode and WP_DEBUG but nothing. The server first loads the cache page and upon refresh I just get a blank page.
    This happens with all sorts of caches, I tried APC, Disk: Basic, XCache and Memcached. All the same result.

    Any more ideas?

    Do you get the blank page while editing the posts? (I do) I have to select the text to see whats written, rest everything works fine. Getting the same problem ? BTW, same happens when I use supercache

    No, I only get it on the non-admin pages, on all of them.

    It appears that knowing what errors are in your error log is key. Meanwhile, this sounds like a memory issue or APC configuration issue.

    I am having this same issue, but it's not just with APC. I'm using disk basic on my local dev environment and APC on my staging site, and they're both doing the same thing.

    It's happening ever since I added some mfunc code to one of my widgets. Ever since then, I can only get the page to load from an empty cache. The next time I refresh, I get a blank page.

    I had the same issue, as well as server error 500, and an engineer looked into it and advised to change my PHP handler from the FastCGI to DSO. I am not advocating you move to DSO because it has security issues when hosting multiple sites on the same server, but it did fix my problem. I run a single site on a VPS so it isn't an issue for me.
