Site move issues

[Moderator Note: Topic title modified. When you start a new topic, use a good topic title.]

Hello,
I recently changed my URL from https://www.mydomain.com/wordpress to just https://www.mydomain.com and I am using the theme “Virtue.” I used the Search and Replace plugin to update the URLs, but it hasn’t updated all of them, such as the monthly archive page. When I click on the calendar widget that is supposed to show monthly archives of my past blogs, I get an internal server error. The first page of my WordPress is working, but when I click on the link to go to the second page or any other page, I also get the same internal server error.

Does anyone know what table I should be looking at to make a fix? Thank you!
