I tried yes. When you said, I tried again, if I did something wrong.. nothing happened. I still get the same error.

Then I followed these steps..
1) I uninstalled WordPress with ftp again and installed it clean.
2) I reinstalled the plugin and tried again.
3) It was added and I made all the wordpress settings again.

– The problem still persists. I uploaded my backup files.
Now my site is working. I’ve seen no problems with any other plugins and other tools. I just observed that this plugin has such problem.
But the same plugin is installed on the subdomain site. There does not appear to be such a problem.
We didn’t want to deal with it anymore because of my work. It started to be a waste of time for me. I don’t want to run another team in this. The problem does not appear from our side. Because when you remove the plugin, it sends emails to its own server. But it doesn’t send with the plugin.

I do not know. If it is fixed with an update, we will wait for it to be resolved. Otherwise we will look at another company with another plugin.

First of all, thank you for your reply.

But there is a problem that we do not understand.

When we enter the same e-mail address to 8laayt.mertsahindemircioglu.com, all of them are working properly.
When we enter the main domain name, it does not work, it gives an error.

When we changed the e-mail addresses, we noticed that while there was no problem in the subdomain web address, there was a problem in the main web site.

We are getting an error like above.

I wonder if there was a problem during the wordpress update that we did not notice?

Such a thing has never happened to us. There is no problem with the e-mail address. When we try this e-mail address on the subdomain site, there is no problem, it works.

The main website is currently not working e-mail address.
It works in the subdomain. Very interesting
