So I'm in quite a pinch right now - have a Wordpress site with over 3,500+ posts with an above average SEO ( niche content, so almost guaranteed Page 1 results )
I initially created the site with another guy and he bought the domain name - since I trust him and I know he's not dodgy at all, I never asked him to hand over the domain to me and ever since the site started in 2012, he's been renewing it without fail.
Fast forward to 2015, due to real life responsibilities, I had to make myself inactive from site development / activities - but still kept the site working in order ( maintenance, hardening, SEO, malware removal etc ) but the site was kind of in a hiatus state - I had no contact with this guy because I usually operate the backend and he does content.
During this time, he was also busy with his new job and stopped writing content, hence the site hiatus.
Now, the domain name is expiring soon and I tried contacting him but have no response after a few days. We have a password sharing service and I found the credentials for the Domain Manager there, but the password doesn't work anymore ( he must've changed it between 2015 and now, because it used to work before - I've logged in a couple of times )
I'm thinking of buying a similar domain name and just switch the site to that new domain, but without access to the old domain, I can't put a 301 redirect on the old domain - and without 301 I'm pretty certain that I will lose the page rank that I've accumulated since 2012.
What are my options? Help! :(
