PHP Warning: date_default_timezone_get(): It is not safe to rely on the system’s timezone settings


PHP Warning: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EDT/-4.0/DST' instead in /var/www/vhosts/adserver/httpdocs/lib/OX/Admin/Timezones.php on line 158


Edit php.ini and add appropriate timezone.


List of timezones are available here:

Firefox 5 Hidden Extension Redirecting Google Searches to Spam Website

Using GooredFix, I was able to remove a malicious Firefox extension. This extension is not all over the internet currently, but apparently present to the few websites I visit each day. It installs without permission and causes every other clicked Google search result to redirect to a fake search engine site.

Deleting HKEY_LOCAL_MACHINE\Software\Mozilla\Firefox\Extensions\\{EFB5AF1A-EB6E-4A28-AEF7-FDD4FBB4B353} -> Success!

Adding additional field to X-cart 4.4.x ACH/electronic check payment method

By default, X-Cart 4.4.x does not provide some additional fields that would be very useful to fight fraud. This payment method is great for a secured x-cart store to collect payment information to be used offline instead of being used with a real time payment gateway. However, offline payment methods require a little extra homework from the store owners to ensure that an account it not being used fraudulently.

The second thing is to enable or allow browser caching on the client’s end. The third is to enable http keep-alive requests. The following will be a brief example of how to enable these features.

Prevent *Zone.Identifier* Files From Windows On Samba Shares

If you have a Samba file server and windows client network, you’ve come across these annoying files at some point. They are added by windows and some say it is for “Security” purposes. Windows may show these files as ‘WDFGH~8’ as the files name. Since that is not the true file name on the Samba system, the files will be untouchable except by the server os. On the Samba server, the file names will appear as ‘:encryptable:$DATA’ ‘:favicon:$DATA’ or ‘:zone.identifier:$DATA’.

To prevent these files from being a problem, you need to add this line to your smb.conf somewhere in the [GLOBAL] section.

vfs objects = streams_xattr

Once added, simply restart and the problematic files will no longer be visible. If you wish to delete these files from the actual file system on the server, you will need to do that manually or problematically if you have the skill to.
