Our company is in the process of changing hosting providers. I am testing the target site before we change the DNS settings this weekend.
Normally Hummingbird works fine, and on the production site, it is working completely normal. On the new host, gzip and browser caching are not working and cannot be activated.
We contacted our webhost who responded with:
Thanks for the credentials, I spent some time reviewing the plugin and looking at some of the things it's trying to test and trigger. Looks like it's attempting to use mod_filter to invoke the functionality of mod_deflate. Why I'm not sure. Seems it would be simpler to set it up as mod_deflate but I'm no developer. Which brings me to my next point.
The plugin doesn't seem to be recognizing the mod_deflate is installed though I've given it the proper path by taking out the improper paths. I would suggest reaching out to the hummingbird plugin to see if they know of any workarounds for this specific issue.
On the gzip page it also says it can't detect the status because Privacy mode is enabled and says to disable that, but where/how do we disable privacy mode?
