You could start by telling us the name of the domain that is having problems.
EDIT/ADD: Also, did you add this via cPanel as an addon or as a parked domain?
WordPress released an update about 10 days ago. I might have messed up your "SEO friendly URLS" .
Try going to your WordPress admin area and turning off the feature. See if that helps. Then try re-enabling the nice URLS. Sometimes you have to turn the feature off then on.
http://fossfamily.x10.mx/Chileflag.gif is how it is stored on x10hosting. Note the lower case "f"
You web page uses it as http://fossfamily.x10.mx/ChileFlag.gif . Note the Upper Case "F"
They are not the same.
If you installed it manually, yes that is how you "uninstall" it.
If you used Softaculous, then you should do it via that tool. cPanel --> Softaculous --> your phpbb install --> should have an "X" icon to remove it.
YOURSITE.x10.mx/foss.css gives a 404 Not Found.
99% of the Web is *nix based.
Microsoft garbage, er products, insist on doing things their own way.
*nix is case sensitive. Windows is not.
On windows, foss.css will get you Foss.css.
On *nix it will not.
Either change your all your css links...
Possibility (ie a wild guess):
x10.mx is served directly by x10hosting
.com goes through CloudFlare ... they detect it is an automated request and so disallow it. Not sure how to fix it if that is the case. You would have to check with CloudFlare.
1. What message did you get for the first code snippet? Hint: adding "--silent" is lousy for debugging.
2. I ran that command (minus --silent)on xo2 and got the error logged as "curl: (3) <url> malformed"
3. url ? Did you give it a url or a path? Maybe try giving it an actual url...
And sometimes the Web can be a bit uneven in updating itself, so perhaps your part of the system is seeing old information.
Try clearing your browser cache and history, and perhaps flushing your DNS cache.
1. Your nameservers are set to another host's
2. Those nameservers point to an account on their servers
3. When I enter your site's URL, the browser takes me to your site on the other host's server
What is the problem?
That link goes directly to your front page for me. You must be looking at a cached copy.
Clear your browser cache and history. Close the browser and then reopen it. Then check again.
