Release Physical Disk Space After Deleting MySql Table

(update on March 04, 2016) Our WordPress blog sites got countless junk comments often. The big amount of junk comments were saved by WordPress into database automatically and caused MySql data tables large sized.

We could delete junk comments manually, or we install some plugins to help us, for example the plugin Akismet can protect our site from spam.

However, no matter which way, if you set you will review all comments manually, the junk comments will still occupy your database space, your data tables are still huge.

I often select an existing WoredPress theme for my blog website, but normally I will NOT use the theme completely, I will change something in the theme due to my own requirement and my own style.

How I changed theme is using WordPress child theme mechanism: it is easy to understand, a child theme, it is a theme which can cover the original theme, but you do not need to write entire theme. The advantage is I also do not affect original theme, I do not need to change original theme directly.

For a child theme, you just create or copy the theme files to another folder which named like “xxx-child” (Note: all theme files located the folder wp-content/themes, the child theme folder also should be in this folder), you use the same file names, and change code in those files:
