Find the plugin that you have just installed from the list and click “Activate” to activate the plugin.
4. If it’s a paid version of the plugin, proceed with the steps described in point 5 and 6 explained in prior method of the plugin installation.

Troubleshooting – common installation issues

While installing plugins is usually a straightforward process, you may encounter some challenges along the way. Among the most common ones are:

1. Permission denied or write error: The write error, also known as permission refused, blocks the installation of plugins and themes. This issue arises when WordPress does not have the necessary rights to write files or directories.
2. Out of PHP memory: If your website uses more memory than PHP has allotted, you may have difficulties installing or activating new plugins.
3. PHP version compatibility issues: A certain version of PHP is needed for some plugins and themes to work. Installation problems might arise from incompatibility.
4. Error establishing database connection: This issue is more serious and can be caused by a number of things, including mistyped login information or issues with the database server.
5. Execution time limit exceeded: If the operation takes longer than the maximum amount of time specified in your PHP setup, an error will occur during the installation of a plugin or theme.
6. WordPress plugin install cannot create directory: It’s a file permission issue that happens because of improper site configurations and settings. WordPress cannot create a folder/directory for your plugin or theme if your file permission isn’t set correctly.

These problems are usually related to installations via the WordPress dashboard. If you encounter these problems, try installing the plugin manually using FTP.
