Recent Posts widget has some older posts at the top? [closed]

I have taken a look and to me it seems that you are not consequent with dates when it is about publishing. (yes I understand that this is probably a new site and you have added all postings at one moment, but just ‘act’ as it was posted on those days/years.)

Take a look at the publishing dates of the postings. I would change ALL those publishing dates to the year it was actual.

Meaning by that:

  • The posting for 2001 has Published: February 19, 2001.
  • All others have Published: December 8, 2015. (seems not logical to me)

A little (very)simplified example:
WordPress request data from the database and the database only “knows” in this case 2 things;

  1. I have 1 post dated with 2001 and 9 dated 2015.
  2. WordPress did a request and I deliver (by Publishing date in this case): in order of year, is the year equal than I look at the dates, are those equal I look at the
    times(and they are for 99,99999% never equal).

By changing those years to the “correct” year (in your case 2003/2004 and so on) it will probably solve your problem already.

Edit each posting, in the Publish ‘section’ at the top right (the meta box) you see Published on: select edit and change just the year, click okay and click now the Update button.

I can be totally wrong, and if so, please let it know and maybe we find another (correct) solution.
