Now I think I have done it correctly - but still a problem.
- All plugins disabled
- Reset to default theme.
Auto-upgrade - The sequence displays as normal and reports that the upgrade is installed correctly.
Then the site is blank.
So is the log-on screen.
Tried following Esmi's instructions above, but the plugins are already disabled and the theme is alteady default.
When the Host company helped me last time, they said that there was a PHP error.
I will get them to restore again, but wold very much like to upgrade to the latest version of WP. Can it possibly be a setting on the server that is causing the problem?
