Information below is old.


I use WordPress solutions in a day to day basis. WordPress comes with a very extensible framework that allows you to add comprehensive and powerful functionality to your Blog system. WP-Optimize plugin is written to simplify your daily WordPress works simpler. WP-Optimize is a WordPress 3.8x database cleanup and optimization tool. It doesn’t need PhpMyAdmin to optimize your database tables. It allows you to remove post revisions, comments in the spam queue, un-approved comments, and many other junk within few clicks.

Below you will find a list of security suggestions to make your website safer. While we are suggesting 14 tips, if you’d like to read more tips and tricks, there is this great article by CollectiveRay has 101 WordPress tips that every blogger should use.

How this could help you?

  • Every time you save a new post or pages, WordPress creates a revision of that post or page. If you edit a post 6 times you might have 5 copy of that post as revisions. Imagine if your post or pages are long and big. It’s a huge number of bytes that is on your MySQL overhead. Now WP-Optimize allows you to optimize and shrink your posts table by removing not necessary post revisions from the database. As example, if you have a post which is approximately 100KB data and you have 5 revisions of that post, the total space wasted is about 500KB. And if you have 100 posts similar to it, you might have 50MB database space wasted.
  • Similar to the scenario described above, there might be thousands of spams and un-approved comments in your comments table, WP-Optimize can clean and remove those in a single click
  • WP-Optimize reports which database tables have overhead and wasted spaces also it allows you to shrink and get rid of those wasted spaces



  • Removal of stale post revisions
  • Removal of stale unapproved and spam comments

Can you help me restore my database?

No I can’t. Please make a backup of your entire database before using this Plugin for the first time. Also backup your database when you upgrade to a MAJOR NEW version (for example – v0.9.8 to 1.5.5 ).

Everytime I clear transient options, it comes back automatically


Divi - Huge Savings

WordPress automatically creates transient options. It is pretty difficult to completley get rid of it. This is why everytime you clean transient options, you will notice new transient options has been created. My best advice would be clear the transient options on a schedule. So, for example it may create 50 transient option in a week and you clear it weekly so the next 50 transient option comes in. Rather than having 100 transient option, you will have 50 per week.

Optimization does not have any effect on database / it is not optimizing the database

Some of the shared web hosting company does not allow scripts to run OPTIMIZE command via SQL statements. If you are hosted with these web hosts, the optimize action will not be able to optimize your database. Please consult your web hosting company regarding this matter.
