Ever tried updating some WordPress plugins and had the screen freeze? Did you refresh madly only to end up with this messages

Well don’t panic. The fix is easy and I’ll walk you through it.

Why this happened

When you go to update a plugin, WordPress puts itself in a temporary maintenance mode state. When you see the “Briefly unavailable…” message, that’s a WordPress-generated notification that alerts any visitors about what’s happening with your site.

This message is normal behavior.

What’s not normal is when your server has a slow response time or for some reason the update script is interrupted (or times out). In that case, the friendly notification morphs into a moment of dread and panic.

How to fix it.

When this happens, WordPress generates a .maintenance file in the root directory of the installation. With normal behavior, the update script completes and WordPress auto-removes the .maintenance file. In the case of an interruption of some sort, this file doesn’t get deleted and the message won’t go away.

The answer? Delete it manually and your live site is back to work now, hope it save your day.

WordPress offers you a nice solution to change your WordPress date format or time format in general settings of your admin dashboard.

How to Generate Password Strong Online

If you want a quick and easy way to make a strong password, there are plenty of ways to generate strong passwords online. Let’s take a look at some of the best that help you how to generate password strong online.


Generator Password Strong is a simple way to make a strong password. You can set how long you want your password to be, from 6 all the way to 2048 characters. This is useful if you want to use it on a site with a strict password length requirement.


LastPass is a service that remembers all your passwords so you don’t have to. Their password generator tool is a useful tool that quickly makes a strong password for you. Just tell it the minimum amount of characters you want it to be, click “Generate”, and a password is created.


Perfect for sticklers of “true” randomness! has provided random number generation based on background radiation, which is one of the more randomly-occuring phenomenon in nature. Their password generator uses this method to become the most “truly random” way to generate strong passwords online.


“Memorable passwords” focus on creating a password that’s easy to remember while still holding up to brute force. If passwords being memorable isn’t a top priority (either because you have a password manager or a stellar memory!), you can use very strong passwords that are sure to keep you secure. The site also generates passwords that can be used for WPA and WEP routers too.

Get Featured Image URL programmatically

Post thumbnails are pretty useful and pretty easy to use in WordPress. Simply add:

To a theme’s functions.php file and you’ll get a Featured Image module on the admin screen for posts which allows you to select one.

It is also very easy to output that image as an HTML <img>:

But what if you just need the URL? Say, you’re going to use it as a background-image on an element rather than a content image. Unfortunately there is no super easy/obvious function for that.

Within the loop, you’ll have to do:

Then $thumb_url will be that URL.

python strip html tags like strip_tags in php

Earlier this week I needed to remove some HTML tags from a text, the target string was already recorded with HTML tags in the database and one of the requirement specifies that in some specific page we need to render it as a raw text.

I knew from the beginning that regular expressions could apply for that challenge, but since I am not an expert with regular expressions I looked for some advise in stack overflow and then I found what I actually needed.

Below is the function I have defined:
