I’m having the same problem. All locations set to zero for 6, 7 days now.
I’m sorry about this. The plugin has one file which needs permission to execute (chmod 755). The file is:
current-planetary-positions/sweph/swetest
To troubleshoot this, if you know how to check file permissions on your server, please double check that this file has correct permission.
All my tests show that the plugin (1.3.1) works. As a last resort, please try deactivating and completely uninstalling the plugin. Then re-install the plugin. Also, clear any cache plugins. I hope this helps.
As a last resort, this may work: deactivate and uninstall (delete) the plugin. Then download the previous version from the WordPress repo here:
https://downloads.wordpress.org/plugin/current-planetary-positions.1.3.zip
Upload that in your dashboard –> Plugins –> Add New –> Upldoad.
That should work in cases where the web server can’t read files compiled with GLibc 2.7.
