I loaded WP Security to my site this afternoon. I started going through the findings and checking things. Not halfway through with the checklist, my site began to not load pages. Now I cannot log in to the back end. The front end error message is, "Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Apache Server at thepetersencompany.com Port 80"
I tried to rename the theme folder to no avail.
I then deleted the amended WP Security .htaccess file and replaced it with my original .htaccess file. Still no website.
I have no idea what to do next to restore my website and correct this issue.
Can you please help ASAP?
