[Plugin: WP Super Cache] The compression still mess up the page look

Donncha: Thanks for the responses…I’ll see about the upgrade. I’ll also try the new files…trouble is I can’t take another downtime hit on my main site…because it always happens during the 3 or 4 hours I manage to sleep each night. Go figure. ??

Anyway…here’s a question: is there a known way to cause this failure? Because if I can pull a trigger and see if it fails, I can do it on one of my lesser blogs and test it that way. But otherwise, it’s upload to one of them and keep trying it to see if it’s fixed–which is sort of an open-ended endeavor.

Thanks much for the help, chief.

widgett – I’ve seen it happen when the gzip headers aren’t stored correctly by the plugin. I cannot for the life of me explain WHY it happens because there isn’t a bug. I’ve logged everything and it still happens. I cannot reliably reproduce it.
So, what I did was add the headers automatically afterward. That fixed the problem on my site.

The only thing I’ve found that might explain why it happens is how PHP shuts down. It destroys objects and runs the shutdown callback functions. Some versions of PHP destroy the objects before the callbacks, others do it the other way. Personally, I’ve seen both happen in the very same version of PHP, and unfortunately they didn’t coincide with missing headers.

What I can say to reassure you is that I haven’t logged any missing headers since I rearranged the code (and that’s what’s in the files above) so I presume none of my visitors saw garbled pages over the last 24 hours!
