I have an installation of wp 2.5.1 in italian on a webhost that limits the number of MySQL queries per hour. So I need to cache dynamic pages.
This wp install is currently running under PHP 4.4.8, but with zlib.output_compression disabled and cannot be enabled via htaccess.
My current wp-config has in it the following lines:
I even made a "cache" folder within wp-contents.
But even after logging off, erasing cookies and clearing my browser's cache, disabling, I don't see at all the famous line: "<!-- Cached page served by WP-Cache -->" at the end of html source.
Before I get back to my webhost's support forum I tried getting my bearings on this new version's support of caching... and, oh boys, I'm a bit pretty much confused.
Aside from the fact that documentation (codex et al.) related to this cache do not report at all any reference to wp version, aside from the fact that not many messages in this support forums have much details on their wp version, aside from the fact that even third-party caching plugins either are out of date or don't tell much about which wp versions works with their plugin...
Aside from all that asides above, what I really would like to know is:
a) Has someone of the developers inadvertently modified/removed from the output of WP the "cached page" message?
b) Or have you decided to use only PHP5's APC feature without even upgrading documentation pages?
c) Or you changed all the hooks to wp_cache functions?
I tried peeking into the code of wp at phpxref but, though it contains only the wp 2.5 files, I've been left with the feeling that cache-related code isn't actually used. I might be wrong, and I'm sure that a deeper and careful look at the code may confirm I'm wrong, but I do not have the leisure to read (and understand) other people's php code for free.
Please tell me what are the requisites for wp to start caching pages, because after three or four days of battling I'm befuddled and I'm not yet sure if it's some problem with wp or if it is my webhost's fault.
Some meaningful/useful reply would be appreciated.
