The exact reason for the errors should be visible in the error log, which you can find in your hosting area. If needed, your hosting provider’s support team can assist you with locating it.
Alternatively, you can enable debugging in WordPress to gather more information. To do this, add a few specific lines to your wp-config.php file. For full guidance and step-by-step instructions on enabling the debug log, refer to the WordPress Developer Documentation at https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/.
In both cases, you should be able to identify the cause in the log file.
You may also try:
– manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.
– If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).`
