In installing wordpress plugin will not always succeed. This could be due to differences between the versions of wordpress and plugins. For that I will provide a solution if there is failure to install the wordpress plugin.

  1. Login into your wordpress database.
  2. You can use phpmyadmin or other tool. Find “Option” tables.
  3. Find the line that the contents of “active plugins”. It is a list of active plugins.
  4. Delete all the contents of the list. All plugins will be in a state of inactivity.
  5. Perform reactivation of plugins that can work well.

Done! your  wordpress can work again as before
