my template was mistakenly deleted when deleting a site.

Hello,

I presume you have HTML export zip files in your Nicepage Templates folder.
You can upload only for further publishing into server.
You can recover your site only with saved project folder in main Nicepage folder or previously exported in zip Project.
If you do not have such files, you can recreate your site by copy/paste the text from HTML pages.
Let us know if you have any other questions.

Specifically what I'm trying to do is upload a created template that I have in the nicepage templates folder in a new site since it doesn't give me permission to upload any html file to continue editing that template. Do I have to recreate the template or is it possible to recover it?
I have worked everything from the desktop application.

Hello,

Please specify your actions step-by-step.
We can only try to recover the site build and published online with Nicepage Online Builder.
Sites created with your desktop application are stored locally in your PC, even if you publish it directly from the desktop application.
If you have deleted such a site from the desktop application Dashboard you can check the project folder, named as Site_1234456 stored locally in your main Nicepage folder.

Let us know if you have any other questions.
