After activating All in One WP Security Firewall plugin
ERROR: Invalid username.
This happened after I changed from the twentyfourteenchild theme to justwritechild theme. I had warily begun activating plugins one by one. On activating aiowps plugin I have been locked out with the persistent 'ERROR: Invalid username'.
From .htaccess file I removed portion from
# BEGIN All In One WP Security to # END All In One WP Security.
In the backup folder I also saw a file "sjlsjslsx_htaccess_backup"
error_log in the root folder says
[08-Jun-2014 18:36:14 UTC] PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 33556046 bytes) in /home/mydoctor/public_html/wp-content/plugins/all-in-one-wp-security-and-firewall/classes/wp-security-backup.php on line 59
One by one I began deactivating plugins, then themes except 'twentyfourteen' and in the end deleted the aiowps plugin. The login page continues to show the same
ERROR: Invalid username. Lost your password?
Attempting to browse from the homepage the error displayed in the browser was
The requested URL /topic/xxxxxpppsss-2/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
The error file on the server says
[Mon Jun 09 02:26:13 2014] [error] [client 188.8.131.52] File does not exist: /home/mydoctor/public_html/cursor.png/, referer: http://mydoctortells.com/wp-content/themes/justwritechild/style.css?ver=1.0.3
phpMyAdmin shows 5 rows
All plugins and themes are latest version.
Why am I locked out of website despite correct username and password?
Is there any salvation?
Do I need a complete website restore?
I will truly appreciate your guidance.
