About Stefan Helander
I was born a nerd! As a child I was fond of fiddling with all kind of thechnical stuff, discovering how things work and often fixing them. As a 6 year old I fixed my grandmothers 220 volts wiring.
The interest in technical stuff grown even bigger in the teenage years where I got my amateur radio license and developed a keen interest in computers.
Today I am proud to be a nerd. It is a part of my profession.
To all of you nerds and geeks out there - remember that nerd is the new sexy! :)

There are several issues that can cause local anchor links to not scroll to the right position. The first thing to check is if you have an id-tag that has the same name as the anchor. In this case the browser will scroll to the id position instead. The solution is to name the anchor […]
Using Gogodigital Cookie Consent plugin for Joomla! version 3.0.2. In the plugin configuration a custom message and submit label was entered and saved but on the frontend the popup only displays the built in message and button label.

Problem: When using ORDER BY or GROUP BY, the swedish characters Å,Ä and Ö is sorted as A and O. Solution: add COLLATE utf8_swedish_ci to your ORDER BY or GROUP BY, for example: SELECT field1,field2 FROM table1 ORDER BY field1 ASC should be changed to: SELECT field1,field2 FROM table1 ORDER BY field1 COLLATE utf8_swedish_ci ASC
Using RSForm! Pro together with the RS!Form Pro reCaptcha plugin stopped working, the reCaptcha does not show up in the form anymore. Inspecting the page shows errors like “Unexpected token <” on line 2 and further down complains that RSFormProReCAPTCHAv2 is not defined. The Unexpected token error is probably caused by a line in the <head> […]
Upgrading a PrestaShop 1.5 to 1.6 resulted in Error 500 when visiting the shop frontend.
