[wp-testers] Anyone having problems with WP SuperCache?

[Kirk M]

I've noticed lately that WP Super Cache has stopped working for both my 
sites at the same time (both running the nightly's auto-update). It was 
working fine until a couple of days ago where I noticed the source of my 
site was showing this at the end for all pages:

<!-- Dynamic Page Served (once) in 1.340 seconds -->
<!-- super cache -->

Usually it states that page was served by cache/super cache and load 
time is normally around .4**.

Pages are caching properly internally (I checked via FTP and my Admin's 
Settings/Super Cache page) but apparently not being delivered by the 
server. Funny thing is, the plugin was working fine in the morning and 
stopped working for both sites by the early afternoon without any 
changes being made to either of my sites or at least it looked that way 
to me. I did post this problem on the WordPress forums (with the correct 
tag) but you know how long it can take for an answer there.

I'm not running any exotic plugins at all (Akismet, Google XML Sitemaps, 
All-in-One-SEO, Ajax Edit Commets, WP-SpamFree, WP-DB-Backups)

Is there anyone else running Super Cache with 2.7-'close-to-final' that 
could check this for me?
