22.214.171.124 Concrete error
Warning - failed to load package with pkgHandle 'theme_slate_packed.zip'. Could not find package controller file: '/var/www/html/website_com/packages/theme_slate_packed.zip/controller.php'
Is the solution to remove the zipped file from the directory so it doesn't try to access controller.php?
I am assuming you have just placed the zipped up package into your packages folder?
Is it a Package that goes in the Packages folder, or is it just a Theme that goes into the themes folder?
You do so by going to "Add functionality" on the dashboard and selecting the package from the list.
If you have successfully installed it, why not just delete the zipped copy?
Have you tried to install the zipped package as a separate entity?
Make a backup of your database from your servers myPhpAdmin section first, this is very important so don't skip this step...
After you have unzipped the package into the packages directory you still need to delete or move the .zip file somewhere outside the packages directory.
Unfortunately this long-standing bug in 5.6 incorrectly looks at *any* file there and tries to find it's controller.php (it should only be looking at directories of course).
Thanks for your help.
