I am locked out of an installation I haven't logged into for ages and can't seem to find a way back in. I've tried the standard lost password dialog, it just tells me I have an invalid key when clicking the reset link.
I have tried logging in following this thread using a third party MD5 hash generator and still nothing. I've tested it both ways and can see the MD5 hash is the same as the one generated by PHPMyAdmin, so that's not the issue.
Is there something more sinister going on here? I updated to the latest version of Wordpress using Softaculous through cPanel. The site itself looks fine, but I'm just worried it might compromised with some type of malware preventing me from logging in. I could always rebuild the site, but it just so happens a client of mine is running into a similar issue, so I'm hoping I don't have to rebuild multiple sites.
