Over the past week, I have tried to diagnose this problem, thinking it was my host, Arvixe (whom I would never recommend to anyone as a host). I have run anti-virus and malware scans against my computer, had my ISP reset my modem and router several times. But every time I try to log in to my WP site, skydiving-encyclopedia.com, I can't even get to the log in screen. As soon as I click LOGIN from my site's Home page, I get a 503 error.
I am able to log in to Paypal, eBay, my Arivxe cpanel account, my Microsoft account, gmail, etc.
I have tried logging in to my WP site using both MozillaFirefox, immediately after a hard boot, and Internet Explorer. Regardless of the browser I'm using, I get the 503 Service Not Available error message. I usually use Chrome.
Using cpanel, I checked the date/time last modified date of wp_login.php. It is the same date/time as many other files in the same folder (in April).
Just a few minutes ago, I went to my home page, and clicked the link "Register Free". It took me to the registration page. I created a new username/password and used my son's email address for it. It created the new user, welcomed me to my site, then took me to my home page (which it's supposed to do). I browsed around the site then clicked LOG OFF.
When I clicked LOG OFF, I got the attached error message, WITH a mention, in the URL string, of my old site, works-words.com/WP/NSM-WIKI.com. This hasn't been my active site for well over a year, though it still exists.
I am now thinking this "may" be a WP problem.
Funny thing, though, another admin on the site can log in as an admin. She lives over 100 miles away and uses a different ISP, and her IP address is different than mine.
I am the "Super-user". . . . and I can't log in but another admin can.
Adam, PLEASE help me.
I am hereby giving you permission to access my site and do whatever you think is necessary to fix what is broke.
This problem has existed for almost a week.
Thank you very very very much in advance.
Mary Todd, Admin/Developer
