Hi elsie,
Thanks for getting in touch. Our plugin doesn’t have a Recommended Events/Eventos recomendados feature or a Recommended Venues/Lugares recomendados feature built in. Those must have been custom built for you. I suspect that the person who did the customizations made the changes within the plugin files.
As we outline in our Themer’s Guide, changes made directly to the plugin files are overwritten when you update to a new version. You need to do a Template Override to avoid this happening. Unfortunately, unless you had a backup of the customized file(s), there is no way to recover the work.
I’m very sorry to be the bearer of bad news, and I hope you can recover the files. You might try getting in touch with the person who did the customizing and see if they can help. You could also check with your hosting provider to see if they provide backups at that level. Good luck!
Best,
Leah
