Fatal Error Messages

I have two blogs that quit working. Both of them return a similar error code. I am not very knowledgeable about scripts so any help to resolve this would be appreciated.

For the blog site https://www.briggsglamourblog.com I get the following error:
Fatal error: Cannot redeclare mh0() (previously declared in /home/darry6/public_html/blog/glamourblog/index.php(1) : eval()’d code:1) in /home/darry6/public_html/blog/glamourblog/wp-config.php(1) : eval()’d code on line 1

And for the blog site https://www.briggsbikerblog.com I get the following error:
Fatal error: Cannot redeclare mh0() (previously declared in /home/darry6/public_html/blog/bikerblog/wp-config.php(1) : eval()’d code:1) in /home/darry6/public_html/blog/bikerblog/wp-settings.php(1) : eval()’d code on line 1

Thanks for any help you can provide.
