New CentOS WordPress install: Error 500
Was asked to troubleshoot a client’s installation technique for WordPress on CentOS 6.x yesterday; they were receiving an Error 500 when they tried to access index.php for the first time. Checking the Apache logs showed: SoftException in Application.cpp:431: Mismatch between target GID (522) and GID (65531) of file “/home/andrea/public_html/index.php” Premature end of script…

New Mediawiki install produces error “Fatal exception of type MWException”
Saw this on a new Mediawiki install where all of the optional extensions were selected, LocalSettings.php had been uploaded to the server and that’s as far as it would go. To fix, open up LocalSettings.php and comment out the line: require_once( “$IP/extensions/LocalisationUpdate/LocalisationUpdate.php” ); You should now be able to refresh the…

MythTV backend DVB adapter error: ERROR_OPEN
If you see the above error when you’re trying to set up your DVB tuner card one cause is that MythTV can’t get access to the tuner card. This can be because there’s another application installed which has access to it, e.g. something like TVHeadend. On XBMCBuntu you can uninstall TVHeadend by running the…

Windows 7 – Stopping a Wacom pen from right-clicking on a long press (aka press and hold)
This is a personal bugbear which I encounter every time I reinstall a W7 OS. The problem is that when you hold the pen down – like you might when you’re trying to highlight text – Windows has a default setting of assuming that you wish to right click, which interrupts the selection you…

Lightroom 4: “Sort” option/dropdown box missing from Library view
This one isn’t related to computer parts for a change but is something that happens to me regularly – I’ll import a handful of photos and want to sort them by capture time, but the “sort” box is missing from the Library view in Lightroom 4.0. You can bring it back by pressing T.…

Network Troubleshooting: Wireless N connecting at 54Mb/s
This one came up today with a customer who was extending her Wireless N home wifi network with a wireless access point. The access point was reporting a Wireless N connection at a speed of 54Mb/s rather than 150 or 300Mb/s, and transfer speeds for anything connected to the access point were only 2-3MB/s…

Asus motherboard BIOS update error: CAP file not recognised EFI bios!
If you see the above error – and you’re selecting what you’re sure is the proper CAP file – chances are you’re trying to use a USB disk formatted to NTFS rather than FAT32. Frustratingly, the error message for a corrupt/non-CAP file is the same as the error message you get when you’re trying…

Error Code 60 on an Asus Z9PE-D16
Today a customer’s Asus Z9PE-D16 wouldn’t boot and displayed the debug code 60 – in this case the problem was that the RAM sticks (8 total, 4 for each CPU) were in the black slots rather than the blue slots. Swapping them across resulted in a boot straight away. Hope that helps someone!
