WP-Exposher Admin page cannot be found

I have just tried to log in today, and I can’t access WP-Exposher anymore. it says “The page can’t be found. It looks like nothing was found at this location” I’ve looked and read most of the posts and feedbacks here and it seems it started after the automatic update for 6.3. I can still access the website, but not the admin dashboard, thus I cannot access the plugins settings. I have been working several landing pages and I do not want those progress to be lost.

The page I need help with: [log in to see the link]
