Hello after developing the site locally on Xampp, I backed up with Akeeba and restored it on my internet server. Unfortunately it does not work because the page remains in charge as if it were waiting for data. The backend works and if I set another theme, the frontend works perfectly with joomla 3.9.
I ask: should I set something in the Perfect theme to make the site work on the remote server? Thank you.
PS. Sorry for my terrificant english

It has nothing todo with the theme.
Maybe you made an error while export or import the SQL database.
