I am trying to upgrade my installation from 7.11.2 to 7.11.3 using the upgrade file SuiteCRM-Upgrade-7.11.x-to-7.11.3.zip
However it is failing with the error stating “The zip file is missing a manifest.php file. Cannot proceed.”
I have checked the Zip file locally and the manifest.php file is there.
I have also set global permissions to 755 and 775 to cache/ custom/ data/ modules/ themes/
followed by a Quick repair as others have suggested online.
However the problem still exists
I have checked the upload folder and the file is uploaded correctly
and there is nothing in the logs relevant to unziping the file.
The environment is a Plesk 17 Onyx, Php 7.3 MySql
