I just thought I'd update where I am on the gzip/opengraph tags thing.
- I have discovered that my host has gzip enabled by default, so for me not having it on in Joomla is not a problem speedwise.
- It also dawned on me (when a friend suggested this work around) that gzip can also be enabled in .htaccess. For an example of what works on my host's server, here is the code
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript text/javascript
</ifmodule>
- I did compare the files in Joomla 3.1.6 and Joomla 3.2.1 and noticed that 3.2 has a file under legacy that 3.1.6 does not - libraries/legacy/response/response.php
I'm no coding genius so this might be a red herring, but a look in that file shows some sort of handling of gzip. I only mention this last item as something that might be important to someone more skilled at the issue.
In the meantime I feel better about the ongoing nature of this "bug" in Joomla 3.2 persisting since there is a work around to still use gzip for speed improvements.
