I upgraded Joomal to version 3.8.8 due to a security update. Directly after upgrading ONLY JOOMLA the site worked well with no issues.
I then upgraded admin tools to 5.1.1 as well as saving a new .htaccess. I made NO changes to any of the setting, just selected Save .htaccess.
I was then not able to access the front end of the site. but was redirected to sedoparking.com. I have no idea why this is happening. Turning off front end protection fixed this issue and the site is once again working.
I see no reason for this to be happening and see nothing in the configuration that references sedoparking.com.
I have included a copy of the .htaccess file that is causeing the issue for your review
