This took me a while to figure out, so I’ll post it here in case someone else ever gets into this problem. \u00a0After enabling WP Super Cache<\/a> for a project at work, we’ve started seeing really weird and really random white page issues. \u00a0WordPress would show a blank page and then a few minutes later it would start working again. \u00a0But then it would disappear and so on and so forth.<\/p>\n

Tracking the issue down, I’ve tweaked the WP Super Cache configuration quite a bit, but that didn’t help. \u00a0And I was sure that it was related to WP Super Cache, since periods of appearing and disappearing were consistent with cache timeout settings. \u00a0Browsing through WordPress support forums (threads one<\/a>, two<\/a>, and three<\/a>) game an idea that it wasn’t just WP Super Cache on its own, but a combination of WP Super Cache plugin with something else on the system.<\/p>\n

After a lengthy troubleshooting process, I think I nailed it. \u00a0APC<\/a> – an alternative PHP cache module – wasn’t friendly with WP Super Cache. \u00a0So, as a short-term solution to the problem, I’ve disabled the APC and now everything seems to work well. \u00a0I’m a bit busy now to troubleshoot the problem further, but if you have any idea of why that could be happening, please share.<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
