When protecting the administrator folder in Joomla using Apache htaccess to increase the security of the website (which by the way is a good thing to do to prevent too interested individuals to peek where they shouldn’t), you might get an error 404 message when trying to access administrator and the expected password prompt never […]
A server I am maintaining stopped during boot on the "Stopping userspace bootsplash" or "Configuring network interfaces". If Ctrl-Alt-Del was pressed the machine rebooted so it was not completely stuck. I tried booting in rescue mode and checked the /etc/network/interfaces syntax but no problem visible there. The solution was quite simple. Boot in rescue mode […]
I made a customized theme by copying the PrestaShop default-bootstrap theme in version 1.6.0.6. After an upgrade to 1.6.0.9 the theme will no longer show the dropdown submenus. The reason is that after the upgrade, the default-bootstrap has been updated but my customized copy hasn’t causing some needed JS files not being loaded. The quickest […]

I’ve found out that the 802.11n high speed wifi / wlan mode (300 Mbps theoretically) tends to cause more harm than good, i.e. the performance in many, especially crowded, wifi environments will be really poor and it is a better option to turn it off. My Compaq 6910p laptop comes with an Intel Wireless WiFi Link […]
On a rather new Samsung Ultrabook series 5 we had intermittent / sporadic connection problems on some wifi networks. The status for the network shifts forth and back between ok and “No internet access”. This doesn’t happen on all wifi networks. It seems the problem is the 802.11n mode, especially in a crowded wifi environment. The […]
After installing VirtueMart on a Joomla 2.5 site, it should occur in the Components menu in the Joomla! backend. In my case, it didn’t show up. The problem can be caused by the Xmap – Virtuemart plugin not being enabled. Solution: Go to the Extensions menu and then select Plug-in Manager. In the filter box, […]
