My Thrive Architect is broken/My website is broken

My thrive architect editor is malfunctioning. I was building a page and was constantly saving it in the thrive architect editor by clicking the save button and every time I did that it said all changes saved.

Only for me to check the live site and the changes didn’t save. Now the changes don’t save on the thrive editor anymore. I even tried building the page on another website and then importing it back, but I can’t because it reverts back to the malfunctioning page.

All other templates I tried importing also end up broken once they are imported.

Please help
