I can not edit a page anymore

Hello together.

Please excuse my bad English. I hope I write understandable my problem.
I had bought the “WellnessCenter Beauty Spa salon WordPress Theme” https://themeforest.net/item/wellnesscenter-beauty-spa-wordpress-theme/12433859. I had worked with it the day before yesterday. And today I start WordPress and can not edit anything anymore. The data is no longer there.
I can call the pages in the backend, but I can not edit them. There is no content to see!
Please urgently for help! THANKS A LOT!


Please be noted your theme is not Gutenberg Optimized. Please check are you using new wordpress 5 block editor or old classic editor. If active block editor then you can try to go with classic editor. You can install classic editor and check is it working. otherwise the best way to get this support is Contact your purchased Theme Author.

Don’t worry just contact Author. Author will be very happy to assist you.
