I was making some changes in my Google GSuite account and the DNS of the server. I don't know if this was related, but I wasn't able to see any captcha widget on login although it was saying that one was required, so I was trapped.
My site is not operational again, thanks to this information.

I already learned the way and finished earlier.I think the fault is with the SEAO plugins, they modify the tables in the database and then cannot be deleted.I have removed from my site 5 databases that SEAO and other developers have created. I am trying to clean files.I have removed patches that were in the original data base, repeating and deprecated tables, which I have no idea why.Deleted bases and files I have gained 12 MG.I have version 4.10.4 installed, I have tried to install version 4.10.5 and it has all come down.I have had to back out, continue with version 4.10.4.I think my site can no longer be updated anymore, the installed plugins do not support the server requirements to install version 4.10.5.At the moment I try to continue cleaning files manually and then I'll see how I do it, I'm considering disabling all the SEAO plugins, and trying to update again.  less

What happens when you apply the same domain to a new recaptcha instance and then find the existing keys in the database, replace those with the new ones and then clear cache?

Back up the database first. Then find the core_settings table. Once in there, find 
core.spam.email.antispam.logincore.spam.email.antispam.signup
or this one core.spam.recaptchaenabled

Clear cache after.
   

I created the new keys. I can't enter the keys.
I have the captcha on the login page, too. It won't let me login in because the old keys are no good.
I need to shut off the captcha from the database.

Unite doesn't allow for database access. Did you mean for SEPHP? I can move this to the correct area if so. 

I accidentally deleted my Google ReCaptcha keys. I created new ones however now, when I try to log into my admin area it says Invalid Captcha and won't let me log in to update my captcha.
Does anybody know where in the database I could turn the captcha on and off?
