- Plesk for Linux
After purchasing and installing a license for the ImunifyAV extension, the Upgrade button appears in Plesk at Extension > My Extensions > ImunifyAV. When clicking on this Upgrade button, it redirects to https://www.plesk.com/upgrade-extension/.
This is a Plesk extension bug with ID EXTCATALOG-161, which will be fixed in future updates.
The ImunifyAV extension does not offer any upgrades.
This button can be ignored.
