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.
