List of really good and important plugins for WordPress

I am listing a few common yet very useful plugins we can utilize for our WordPress websites:

Limit Login Attempts

Limit the number of login attempts that possible both through the normal login as well as using the auth cookies.
WordPress by default allows unlimited login attempts either through the login page or by sending special cookies. This allows passwords (or hashes) to be cracked via brute-force relatively easily.
Limit Login Attempts Reloaded blocks an Internet address from making further attempts after a specified limit on retries has been reached, making a brute-force attack difficult or impossible.

Features:

Limit the number of retry attempts when logging in (per each IP). This is fully customizable.
Limit the number of attempts to log in using authorization cookies in the same way.
Informs the user about the remaining retries or lockout time on the login page.
Optional logging and optional email notification.
Handles server behind the reverse proxy.
It is possible to whitelist/blacklist IPs and Usernames.

Fix Magento 2 – php cli error on cpanel or other hostings

The problem:

On a fresh install of Magento2 on cpanel based hosting, you receive the following error while running any command on SSH

[eee@e1 www]$ php bin/magento cache:clean
X-Powered-By: PHP/7.0.31
Content-type: text/html; charset=UTF-8

bin/magento must be run as a CLI application
[eee@e1 www]$ php bin/magento setup:upgrade
X-Powered-By: PHP/7.0.31
Content-type: text/html; charset=UTF-8

bin/magento must be run as a CLI application

The Solution:

You have to point php to correct binary;
Use the following code in order:
First, open the file which can alter the runtime variables like .bash_profile or .bashrc

cd ~ ; nano .bash_profile
OR
cd ~ ;nano .bashrc

Go to last line and paste this (depending upon php version change ea-php71 or ea-php70):

alias php='/opt/cpanel/ea-php71/root/usr/bin/php'

Save the file and exit the editor.
Log out and login again OR use the following command

$ source ~/.bashrc

If you are not sure about current php version, use which php or php -v command. If you think the cpanel configuration is the issue, fix EasyApache 4 PHP cli issue. With this way you can fix the setting and enable the new php version
