My Latest News

It’s 20th September 2017 and my Gravityscan Badge is back, after 8 days, as you can see. I’ve learnt a lot in the last week. I now understand that my IP address is shared so I take the rap for the actions of others. For now I’ll wait and see what the future holds. You may see the badge come and go as a consequence.

Well on 12th September 2017 I had a Gravityscan setback. My 1&1 server was found to be on a spamming blacklist. Why I don’t know. Gravityscan have not found malware on my site. I have now deployed Sitelock too and that hasn’t found a problem with my site either. I will automatically be removed from the blacklist after 7 days if there are no more spamming incidents in the meantime. Meanwhile I don’t have a Gravityscan Trust Badge but I do now have a Sitelock Badge.

I’m currently trying to improve older posts which have fallen foul of theme changes and don’t have satisfactory images.

To improve site security:

I consider the action I took on 13th August 2017 to harden my header against Cross-site Scripting, Cross-site Tracing, Clickjacking, MIME Sniffing and Directory Listing by sending messages to the server from my .htaccess file to be ineffective. I will try again.

I took on the benefits of Gravityscan as of 28th July 2017. It checks this site for malware every day as you can see from the Gravityscan Trust Badge in the page header. Gravityscan have changed the date display to an international format yyyy-mm-dd. Selecting (clicking on) this badge will take you to the Gravityscan website.

On 30th June 2017 I took the step of securing my server communication with browsers by using 1&1 Internet’s TLS and certificate services. So now my main URL is HTTPS://helpfulcolin.com. Readers will see a padlock in their browser as a consequence.

I have also taken two more domains onboard “helpfulcolin.co.uk” and “helpfulcolin.uk”. Connections to them use HTTP not HTTPS but security is maintained by them redirecting links to “HTTPS://helpfulcolin.com”.

Site Construction

The site helpfulcolin.com was originally built in September 2011 by Digitalog© using the Side Blog theme and handed over to Helpful Colin by his mentors (see their links below) in December 2011. It was changed to a ‘Twenty Fourteen’ child theme in February 2014 by Helpful Colin.

The latest major change took place in December 2015 when WordPress version 4.4 became active and Helpful Colin changed the theme to the ‘Twenty Sixteen’ theme which is designed to look good on all screen sizes. Although this may have improved the blog for mobile users it has removed some functionality available in ‘Twenty Fourteen’.
