I have the same problem as reported here by inter135, who started this thread, and robbinsg. A few things relevant to this: Firstly, inter135, if you still have the same problem, this might help:
If you can't login directly to the Direct Admin app using your old credentials, try again appending "/user/domains" to the address provided above by Eric. i,e, the address to go to is:
https://x12.x10hosting.com:2222/user/domains and try logging in there with your old username (not email address) and your old password. It worked for me. (In your case, you may need to change x12 to x13. I think it depends on which server your webhosting account resides on.)
I hope Eric is still monitoring this thread, because I have followed his advice by placing a file named x10hosting.txt containing my new contact address in my public_html folder. I have also sent Eric (I hope you're listening, Eric) a PM ("conversation") to advise you of this. Please tell us what should be done next to create a new password for logging in at the hosting account portal.
Eric, can you please also answer the following two questions:
1) During the long period when x10hosting was doing extensive maintenance work on the hosting servers, it suspended the requirement to login at least monthly. Has that work been completed, and if so, has the monthly login requirement been reinstated? If it has, does logging in to Direct Admin count as activity to prevent our hosting account being suspended for inactivity?
2) In case a need arises again in the future to notify x10hosting of a change of email address for contact purposes, what is the normal mechanism for doing this?
