GD Booster notifications

Hi,
I was having issue with GD booster not working, as when viewing page source there were notes at the bottom of the file and site was still slow.

So, I deleted GD Booster and reinstalled and added gzip to htaccess.
Site does seem slightly faster and i now get notes in viewing source.

However, here are the notes for Home page and a few others:
<!– GD Booster is NOT caching this page, because the PHP constant

DONOTCACHEPAGE

has been set at runtime. Perhaps by WordPress itself, or by one of your themes/plugins. This usually means that you have a theme/plugin intentionally disabling the cache on this page; and it’s usually for a very good reason. –>

Also get this note for most pages:
<!– GD Booster is NOT caching this page, because GD Booster is unable to cache already-compressed output. Please use

mod_deflate

w/ Apache; or use

zlib.output_compression

in your

php.ini

file. GD Booster is NOT compatible with

ob_gzhandler()

and others like this. –>

I do not have other caching plugins installed.
