As @NeilUK said not with RapidWeaver alone. Any plain text editor will work for creating an .htaccess file. It must be plain text and called .htaccess with the dot.
Once created you will need an ftp client such as transmit(paid) or FileZilla (free) to place the file on the server.
“We added a code in the main .htaccess file to remove the errors in gtmatrix.com and it worked for the home page. For the inner page the same errors are showing and I added the same .htaccess file in the folder and tested that page. But the errors are still there. It seem adding the .htaccess file didn’t work there.”
Using the code I had pasted above, he says he was able to resolve the “Enable gzip compression” and “Leverage browser caching” errors on the home page…but it didn’t work on the About Jaacob Bowden & His History page.
These are the drop-down details of the “Enable gzip compression”:
OK,
Never heard of that test tool, but I just checked:
And it is showing compression (gzip) is on.
Also, rain a speed test and it shows it turned on as well, not to mention the pages are quite light in wieght.
I don’t think I would have turned gzip on that way unless that was the only way. As Scott pointed out there is usually an easier way in the cPanel, normally under something like Website Optimization icon on cPanel.
There’s also usually some sort of “Cache Manager” option to setup cache expiry info.
You didn’t say who your hosting company is, so I don’t know what options you might have.
And of course, you could set up a CloudFlare account and that would take care of both those issues and more.
