The connection was interrupted

Hi!

I don’t know what version of wordpress I am using…

So I am no good at website jargon and when searching these forums I cannot find a way to fix my problem that I understand – if there is even an answer for my problem in these forums at all.

I asked my boyfriend in Australia to help me solve some problems with my website (he couldn’t). Since he tried to help though, I cannot login to my site from my wifi (I am in the US). The strange part is that people in Australia can log in, but I get this when I try to get the login page:

This webpage is not available
The connection to littleytheatre.co was interrupted.
Here are some suggestions:
Reload this webpage later.
Check your Internet connection. Restart any router, modem, or other network devices you may be using.
Add Google Chrome as a permitted program in your firewall’s or antivirus software’s settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again.
If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don’t believe you should be using a proxy server, adjust your proxy settings: Go to Applications > System Preferences > Network > Advanced > Proxies and deselect any proxies that have been selected.
Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.

It is not that I need to reset my password, it is that I cannot even get to the page to enter my password.
I have tried getting there via Safari, Chrome and Firefox and can’t on my computer.

Once this is solved I would also love some help in solving some other challenges I am having.

Thank you,
Mischa
