This error message could appear while installing different Joomla! plugins. It could happen when adding new plugins, modules, components, or templates. The error message’s overall meaning is that the extension file is corrupted, however, there are two usual causes of such problems.

1. If you are trying to install an archived extension, your hosting server’s zip file may be having issues. You could try the following as a solution:

Locally extract the archive on your computer, then use FTP to upload it to your hosting server. Afterward, select the option to install the extension from a server directory. Through Joomla!’s normal Install extension interface, you can choose that.

It should be noted that since zip is installed and functional on every server, this cannot occur on SiteGround servers.

2. There are errors or gaps in the extension package. This is the most likely reason if, despite using the previous instructions, you were unable to install the extension. Therefore, it is advised that you never try to use the package.

Why do People Use Joomla?

The explanation is straightforward, easy, and effective. This gives the developer a ton of flexibility and customizability, even though WordPress is equally easy to use and customize. When installing Joomla, you have the option of enabling or disabling the modules. Additionally, it is safer than other CMSs.

Joomla also heavily relies on templates; if you don’t like how the site looks, you may install different templates from a variety of online sources. This expedites the process of designing the website’s front end.
