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.

This is how I configured IPv6 address received dynamically from my ISP. This is not to be confused with using a 6to4 tunnel service which is something completely different. In this case, a real IPv6 address is received using DHCP6 or SLAAC from the ISP. In this setup the IPv6 LAN side is bridged with […]

If you do not remember your credentials, you should contact your web host.” To solve this, add the following line to your wp-config.php: If that doesn’t solve the problem […]
The Joomla! extension iFAQ from Ideal Extensions is a nice way of building a FAQ (Frequently Asked Questions) section on your website. One feature I am missing though is to be able to select wether a FAQ list of articles should default to all open instead of closed. This is a simple workaround. Add a […]
After maintenance even though setting to shop to active, frontend still shows maintenance mode. This can occur when multistore is enabled. Solution: Use for example phpMyAdmin to access the shop database Find the ps_configuration table Find all records with the name PS_SHOP_ENABLE and change them from ‘0’ to ‘1’ (there are probably more than one)
Joomla breadcrumbs only dislplaying “Home” for an article. JoomSEF was installed causing the issue. Solved.
WordPress just showing a white page means it is experienceing PHP errors. When it occurs after a site has been moved from one hosting to another it can be caused by several reasons.
