I am trying to migration and then upgrade an old WP 4.7.3 multi-site platform originally housed on a Windows/Linux server configuration. The Linux RHEL 8 server was for the web server and WP.
Current configuration: PHP 5.6.40, Mariadb 5.5.68.
Target Host server: Installed the highest versions compatible with WP 4.7
New Window Server 2022: MySQL/MariaDB 10.5, PHP 7.2.9 (allows phpmyadmin to work with WP 4.7)
Already tried All below on my test.exampl site:
- Checked the internet connection and Host firewall settings.
- Cleared Browser cache
- Disabled firewall
- Not using VPN
- Flushed the DNS
- applied .htaccess and removed
- disabled all plugins under wp_content directory
- Renamed all Themes, also.
- Copied all wwwroot WP files from Production Site, again.
- Changed the mysql wp_options,URL settings
- Configured IIS
- Installed HEIDISQL 12.10 to import nssansca tables databases.
After frustrating many tries of not being to get the wp_admin/wp_login page, I decided to edit the wp-config.php, wp-login.php and wp-settings files on my own.
I have one success: by turning on Debugging and commenting OUT
the define entries for multisite, along with the Auth keys set to '' in wp-config.php file.
Never this in online searching.
I was able to establish connection to 1 wp-admin wordpress sites login page. BUT only for 1 site and not the Super-User account over all domain sites.
How can upgrade all of the sites? Does the MultiSite need to be in the wwwroot directory?
