WP Super Cache — Content Encoding Error

if you are getting the below error:

Steps to fix this:

Go to the advanced settings page and make sure compression is disabled. 

 Since the host already ‘gzip compresses’ enabled, asking Super Cache to do that for you again ends up giving out these weird encoding errors.

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

* Please contact the website owners to inform them of this problem.

Avoiding the Not Secure Warning in Chrome

Chrome will have following impact after the version 65:

1. The websites that having Symantec-issued TLS certificates older than June 1, 2016 and that must be replaced
2. Chrome will mark non-secure pages containing password and credit card input fields as Not Secure in the URL bar.

To avoid this you need to install the SSL on the website that contains containing password and credit card input fields. 

For testing:

1. Please install the updated version of chrome - https://www.google.com/chrome/browser/canary.html
2. Configure Chrome to show the warning as it will appear in January 2017, open chrome://flags/#mark-non-secure-as and set the Mark non-secure origins as non-secure option to Display a verbose state when password or credit card fields are detected on an HTTP page. Then relaunch your browser.

WordPress - Briefly unavailable for scheduled maintenance. Check back in a minute.

Briefly unavailable for scheduled maintenance. Check back in a minute.

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.

Here are the steps:

• Log into your web server via FTP or your web host’s control panel.*
• Locate the root of your WordPress install (this is where you’ll find folders for wp-content, wp-admin, and wp-includes)
• Look for a file called .maintenance
• Delete it
