Guess, I’ve now found it. But, sry for being slow, I don’t understand the instructions:
“This message is not for first using this WordPress theme.
If you are using this WordPress theme right now we recommend these steps:
Install new version as a different theme for backup previous version.
This new version has a different version number and different folder name.
So don’t change the folder name and install it, WordPress will
install this version as a different theme but your previous settings
still stayed.
The translation files are located in the languages folder under theme folder. Copy your translation files ( .po and .mo ) from previous version of the theme.”
I just updated the Read file and it has reset my website to the original setting, I went through extensive coding to make changes for my original site.
