How to create a SSL certificate on Mac for my Wordpress blog installation on localhost (OS X Yosemite)?

Fri, 20 Jan 2017 02:48:29 +0000

I created a clone of my Wordpress blog on my Mac copying the exact files and the site structure as well as the database.

The front page of the blog shows up alright, however I can't access wp-admin/ and can't access wp-login.php either. Instead I get the error:

Safari Can’t Open the Page

Safari can’t open the page “https://www.mynewawesomeblog.com/wp-login.php” because Safari can’t establish a secure connection to the server “www.mynewawesomeblog.com”.

Since Safari says it can't establish a secure (https) connection, I understand I need a local SSL certificate.

My question is how can I create one?

SQL0204N "BP32K" is an undefined name. SQLSTATE=42704

Fri, 24 Jun 2016 01:31:27 +0000

While configuring the ODM RES database during a custom IBM ODM installation (aka iLog JRules or WODM), I'm encountering this error:

DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned:

SQL0204N "BP32K" is an undefined name. SQLSTATE=42704

This happens right after executing the following SQL command:

CREATE TABLESPACE RESDWTS PAGESIZE 32K BUFFERPOOL BP32K

And then rest of the script execution is also broken because of the above error:

CREATE SYSTEM TEMPORARY TABLESPACE RESDWTMPTS PAGESIZE 32K BUFFERPOOL BP32K

DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned:

Any help will be appreciated.

How can I execute a .sql file on DB2 using the command line?

Fri, 24 Jun 2016 01:16:01 +0000

Since DB2 control center the only built-in GUI tool is discontinued by IBM, how can I run a DB2 .sql file using the command prompt on DB2 10.x and later?

How can I edit hosts file on my Mac with a GUI tool like TextWrangler?

Sun, 19 Jun 2016 08:29:38 +0000

I'm struggling to edit my hosts file on my Mac (OS X Yosemite) which is located at /etc/hosts using TextWrangler.

When I open the file first, I receive a dialog box asking "Are you sure you want to unlock "hosts" ? You aren't a member of group wheel."

I click "Unlock".

I edit the file and then try to save, but then I receive another dialog box with an error saying:

This operation couldn' be completed, because an error occurred.

The authenticated save for this file failed (application error code: 200004).

Any suggestions to solve this?

How can I enable multi-site feature in WordPress 4.5?

Sun, 15 May 2016 08:18:07 +0000

I have just installed a fresh Wordpress 4.5 on my web space with the objective of having multiple blogs in one single installation.

As far as what I know, Wordpress µ (MU) is integrated in the regular Wordpress since version 3.x , but how can I activate it? I see no setting neither in the Dashboard or in Settings.
