Customizing and coding changes:

Hey there, I have been asking quite a lot recently but there is so much awesome stuff to do^^

The following questions are mainly regarding coding and or compatibility issues:

I am running GD in a multisite under “mysite.com/guide”

1: You guys added the awesome GD booster and there is the option to activate GZIP Copression inserting a code snippet in .htaccess, so i just add it behing the current .htaccess code?
Considering I run a multisite on a sub directory base, it will compress the files in all WP? (would be awesome…).
1.1: Are you aware of any plugin incompatibilities with GZIP?

2: Also You came up with a way to sort the listings by Price (https://wpgeodirectory.com/how-to-sort-listings-by-price/) where the code snippets have to be added/changed into the functions.php.
2.1: When Any Update is done, will this be affected/resetted? Still works with the new update 1.6.6?
2.2: How are listings sorted? First by Price, then subsequently by rating within price categories (Best to worst of premium, best to worst silver etc…)? (If not would it be possible?
2.3: Is there a way to set a color or overlay specifically for “Price category X”?

3: The Twitter Feed snippet you guys show with the update release (https://wpgeodirectory.com/custom-field-improvements-in-new-v1-6-6/ ) would need to be added where?

4: Can all these snippets be added with the code-snippets plugin? or shall i just go the filezilla way…? I still assume that updates do not affect the code no?

5: Considering again that it is running on a sub directory of a multisite, will Cache plugins activated on the other directories affect GD (Should not because different entities no?just going safe here…). Also Plugins Like Yoast, Jetpack, you guys know the usual suspects from your known issues site… I have been reading for like hours through issues etc, but couldnt figure it out for my multisite setting

Yep Noob here…

Thanks a million, You guys are the best
