Title: “Plugin installation failed.” Last modified: June 26, 2020 --- # “Plugin installation failed.” * Resolved Anonymous User * (@anonymized-15482330) * [5 years, 11 months ago](https://wordpress.org/support/topic/plugin-installation-failed-23/) * I cannot install Clean Talk on two websites that I manage. * The error message states, “The package could not be installed. No valid plugins were found. Plugin installation failed.” * They’re hosted by different companies so the cause is not likely to be the hosting. * Both are WP sites using Divi theme. I have the plugin installed on other sites using Divi, so that too is not likely the cause. * My Clean Talk license is active and still has several available sites, so that’s not the issue. * Help please. - This topic was modified 5 years, 11 months ago by Anonymous User.
