Hi Bel, thanks for your reply.
1. This test site is wmap.byethost32.com/wmap/ , where you can perform all the necessary checks (backup copy is available).
2. Plugin Temporary Login Without Password I installed on this site
3. I opened a support ticket on our website, and shared the test site login link in it.
4. I checked my test sat wmap.byethost32.com/wmap/ and now it opens correctly, both the control panel and its public part. When checking the site settings, I did not find any problems, here is a screenshot:

This test site is located on a free hosting, perhaps the problems arose because of this.
Let me know if you have problems connecting to it.
Best regards
