I made no changes in permalinks. Clicking Save Changes did nothing. I have only one plugin (Contact Form 7), and the issue occurred before I installed the plugin.
This domain had a Weebly website prior to my installing WP and your theme. The tech support at FatCow hosting told me I could just move all the old files from the root directory to a new folder, which I named Old Website. It was the only way to remove the Weebly website. I did not create an index.html file on my own. I moved the old files and then did a clean install of WP and then your theme. This is only the 2nd website I have installed so am not that proficient in this.
I will download the old files to my computer as a backup and then delete that folder with the weebly website from the root, and let you know if that helps.
