I think I accidentally deleted the plugin. Tried to reinstall but says the destination file is still there, so it will not reinstall. How do I fix it - preferably without losing all of my data!?
Data should not be lost as it is all stored in the database and not affected by changes on the file system.
I suggest you don’t use the WordPress plugin updater but sFTP or maybe web FTP provided by your hoster. Download the files manually (https://wordpress.org/plugins/podlove-podcasting-plugin-for-wordpress/#installation), then upload them to the plugin directory.
you are beautiful - thank you!
