I have been working this problem for over 3 hours and am still getting this error. This is my up-teenth Betheme install, and never have I seen something this persistent. Please advise if this is a theme issue.
(1) Imported BeResume. The site is only 2 pages, with a very long home page.
(2) Using muffin builder
This is what I've done to fix the problem:
(a) there is a phpinfo.php file on the site now, feel free to look at it.
(1) deactivated all plugins
(2) switched to Twenty Seventeen
(neither of that worked, still 404 on home page update)
(3) Added .user.ini to site's root (Using Godaddy shared, this is preferred over php.ini)
Successfully increased Memory and max Vars:
max_input_vars: 5000memory_limit: 512M
(4) Deleted .htaccess via FTP. Changed permalinks to something else. Changed it back.
(These two things alone have always fixed this particular problem.)
(5) Uploaded fresh Wordpress files for version 4.9.1
(none of this has worked)
(6) Sat on phone with GoDaddy for 1.5 hours.
(7) Since I'm on shared hosting, cannot change Security Mod (as suggested by many blog posts)
(8) Recreated the page from scratch by creating a whole new page. I hit save every so often but got the 404 about 1/2 down the page.
Another of your suggestions was to reset the database since we imported a template. I'm concerned about doing this because I do not want to lose my work.
Please advise as I'm beyond frustrated and don't know what else to do.
