My password stops working after creating a new site despite working during setup

Hi,

I’m in the process of migrating our company website from a trial address to our main address. We are using a 1-click wordpress solution at one.com (which is our web hosting service). Some time ago I created a temporary website to work out how we wanted it to be and to show our CEO and other interested parties our draft, and a few weeks ago I started the process to make it live at our main address. To do this I created a new 1-click wordpress site at one.com and started copying over our site and database to the new location (after backuping everything up of course). I’m fairly new to wordpress however, and the site I’ve made is a multipage site so despite following some guides I made some mistakes in the process, and figured that the easiest thing to do was to remove the new site and start again. This happened a couple of times but I learned something new each time (like for example that subdomains that I used at first wouldn’t work for our new address and thus I needed to create a new multisite that used subdirectories instead), but fairly soon I started to experience some strange issues. The password to log in to /wp-admin worked during the setup, but then I couldn’t access the dashboard with the same password any longer. I thought I had only made an error entering the password when creating the site, so I created a new site again using copy paste to make sure the password was correct, but the same thing happened. I also started to get asked to do some simple math during the log in process to prove that I’m human which I never did originally. I assumed that this issue might be caused by creating all the new sites, which might make me look like a bot or something.

I was running out of time since I was going to be out of office for a few weeks, so I created a non-multisite copy of the main site, edited the main links to other pages and things like that in the database directly to at least have a semi working website during my time off and get to work on it when I got back. I figured that maybe the limitations that are locking me out of my own website would end when some time passes.

Well, now I’m back and I’m still having the same issues. How do I solve this? I can’t have a webpage that I can’t access to edit anything in the page. Editing everything through the database and through the files in the directory is really cumbersome and not the way I want to do things…
