Very frustrating, I have now deleted the iThemes Security plugin and installed “All In One WP Security & Firewall v3.7.1”.
So far all is good, site access speed is faster and features are similar, some are better and less prone to errors relating to being locked out of your admin.
Why would you abandon one of the most successful plugins for a obviously flawed rollout of a plugin.
****I did get warning messages to alert me of the change and espousing the greatness of the “New” programmer they had brought onboard, however the fact of intentional or un-intentionally disabling and opening websites to attack is an unconscionable and libelous act of negligence.
