     from #SITEGUARD_PLUGIN_SETTINGS_START
 to   #SITEGUARD_PLUGIN_SETTINGS_END
  2. Please delete the whole “siteguard” directory from the “/wp-content/plugins/” directory.

Admin Page IP Filter or Rename Login does not work.

If the Web server is not Apache or “mod_rewrite” is not loaded, these 2 functions does not work.
Please contact the server manager and ask the load of “mod_rewrite.”

A part of the WordPress functions are suspended.

Disable Admin Page IP Filter function and try again. If it enables the function, Admin Page IP Filter is the cause.
It the URL (wp-admin/? ) is known, add it to the excluded path of Admin Page IP Filter. If the URL is unknown, disable the function.

How is the number of characters of CAPTCHA changed?

The number of characters of CAPTCHA is fixed to 4 characters. It is unchangeable.

How is the error message at the login failure changed?

The error messages at the login failure, login lock, and first failure of the fail once are fixed. They are unchangeable.

Your access is locked without login failure.

The login lock locks your access based on the connection source IP address.

If the accesses from companies, schools, and so on use a proxy server, all accesses using the proxy server have the same connection source IP address. If the number of login failure of the users using the proxy server exceeds the specified number, the login lock occurs and the users using the same proxy server cannot login.
If such login lock often occurs, try to decrease the determination period or increase the number.

What does the Fail once function mean?

Password list attack is the illegal login attempt attack using the combination of the user name and password illegally obtained from other services.
Different from the brute force attack which attempts the illegal login changing passwords one by one for one user name, there are many cases in which the login succeeds when one password for one user name is attempted. Such attack cannot be prevented only with the detection of the sequence of login failure.
The fail once can show that an attack may fail because once the correct login attempt fails. The function does not allow the login without 5 second interval if the combination of the same user name and password is attempted consecutively 2 times.
This function seems to need much effort, but both the input of CAPTCHA and the 2-step authentication are small efforts and they are equal.

IOS or Android apps(WordPress) are no longer available

Please disable the login CAPTCHA and Fail once. *from version 1.2.0, you can now also be used to enable these.

Function that was to ON, was unawares become OFF

“Admin Page IP Filter”, “Rename Login”, and “WAF tuning support”, has achieved a part of the function by setting the .htaccess. If you delete the .htaccess file or that portion of the .htaccess is deleted, it will not operate normally. In the version of Version1.2.2 later, so as not to be in this state, there is no relevant portion of the .htaccess, the function has been turned OFF, automatically.
