Hi, I recently installed W3 Total Cache Plugin on my wordpress blog. I have enabled everything (Page cache, Minify, Database cache, object cache, browser cache, cdn, varnish, cloudflare), but I am getting this error: Later I realized that CDN configuration is not done. But I am unsure of what to put in (FTP path, Replace site hostname with)?
This is something that you need to ask your host. Every hosting provider and hosting account is different. There is no way for any of us to know what settings are best for your particular hosting provider.
they are also unsure of what to put there. They are only able to provide details for (FTP hostname, FTP username, FTP password). They are unaware of the rest things (FTP path, Replace site hostname with). I will try to put those details, but I don't have idea of what does these things mean. Can you explain me what does (FTP path, Replace site hostname with) mean?
That is a really crappy host. These things are what they do. I use that plug ins as well and I don't have those settings on. If you don't know what FTP is, it's how you access the files on your server using a 3rd party app like Filezilla: http://en.wikipedia.org/wiki/File_Transfer_Protocol I'm also not very versed on server settings and administration. I had my host set it up for me. Sorry I can't help more. Maybe try the plug in forums: http://wordpress.org/tags/w3-total-cache
I have contacted Web host provider, they said they do not provide CDN capabilities. Can anybody help me of how to completely uninstall W3 Total cache plugin?
You don't have to have that. The plug in still works just fine without it. That is merely an additional option for people with those server settings. But if you want to remove it, deactivate it, remove it and then you have to go into your .htaccess file and take out all of the code that it created until you are left with the default WordPress .htaccess information like it is here (assuming you don't have any other mods to it) : http://codex.wordpress.org/Using_Permalinks#Permalinks_without_mod_rewrite You also have to remove the w3-total-cache-config-yourdomain.com.php file from your wp-content folder. That should do it. Edit, there may be a line in your wp-config.php file as well. But I'm not certain.
