I have installed this extension and PHP status page shows the extension.
However I am unable to use the Project installer - this is the message as below:
Sorry, it seems that the PHP .zip extension is not loaded on your server. You will not be able to download any projects using Project Installer until this is fixed. Please contact your website administrator.
Curiously, the status page does not show zip . . .
What am I missing?
Thanks for the follow-up @abqgman! That is a strange problem. I wonder, when you ran update.php were there updates that were needed for your system? Or did the updater tell you that no updates were necessary?
If the latter, then what Backdrop needed was to have it's caches cleared - as those are cleared automatically when visiting
