ok so reading your 2nd post i see you are using the chatbox system made by Avac Webchat
Right that system is just a Plugin javacode to make our own chatbox a little better...
Now to get your chatbox back to the way it was you only have to remove the javacode saved in your Javacodes...
Now the CSS files for the chatbox in your CSS fig 2 are just a new code to make the Avac Webchat look better or make a change to the look of the box and layout so deleting them will not be a problem... remove all the chat box codes and your see your chatbox as it was the day it was made on our servers and when you first turned it on...There is no more to it than that..
basic chatbox
Color and shape may be a little more like your forum thou
Now about you hosting your own files to make a change to your forum and its look.
Let me see if i can make it more easy for you to understand.
In the screen shots i made last time think of fig 1 and fig 2 ok nothing more...
In fig2 this is a nothing but a file system that makes the default code change it sort of over writes the basic CSS found in fig1.
No matter what you do you can not Delete them files as The forum is made to run them no matter what.
Now when you first make a forum from day one if you pick to just use the basic forum. it looks like this.
Now the CSS files page is Blank like this.
Now to make a change to the main skin you need to tell your Basic CSS files to stop working and take the new command.
This is Done by making a new code in the Blank space in screen shot 2
By adding the code there it tells the basic code to stop working and use the new one.
Now the basic Chat box code is saved in the basic CSS you can not change that No matter what...
Now you want to host the file to make a change to your forum by using Google right ??
well you need to make a javacode or some other type of code to make your forum read from that host not the Main CSS file......"FIG2 "... Forget about the basic CSS as this is going to be updated later in your Hosted files.
Now in your forum you have 2000+ codes all running in this page ...
So what i am saying is Take the code you have in this box and make a copy of it and save it on your computer in say Notepad.
Now host the files you have made a copy of on your own host and link it to your forum.
Now when you delete the codes from that box
"FIG2" it will make your forum go to default Codes now your hosted files from google will be inplay..If your forum looks a mess then you have not made the right system to make your forum read the CSS files you are hosting..
So now if you can not get your Hosted files from Google to work you still have a copy of your CSS files on your notepad on your computer to go back in the empty CSS
"FIG2" files again ready to put your forum back to how it was before you made the change
Yo Don't have to host the Basic CSS files on your host system as this is fixed in to your forum and running 24/7 all year round no matter where your your new CSS files are hosted. you can not run your forum without it
