Hi carry out the following instructions.
– Deactivate the plugin.
– FTP to your host and make sure the following folder all-in-one-wp-security-and-firewall has been deleted. If not delete the plugin folder.
– FTP the .htaccess file to your computer and edit and remove all the code between and including the tags:
# BEGIN All In One WP Security
# END All In One WP Security
– Log into phpMyAdmin and locate the database for the website you are having problems with. Look for any table entry with the following name aiowps and delete those tables.
There should be 5 tables associated with this plugin:
aiowps_events
aiowps_failed_logins
aiowps_global_meta
aiowps_login_activity
aiowps_login_lockdown
Let me know if you need more help.
Regards
