Log in error issues

Hi,

Have you tried following suggestions?

1) Try manually resetting your plugins (no Dashboard access required) using following URL;

https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F

If that resolves the issue, reactivate each one individually until you find the cause.

2) If that does not resolve the issue, access your server via FTP 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).

Thanks,
