Hello Rikard ,
I didnt restore a backup , i just uploaded an older version of the theme via FTP.
I had version 4.8.3 when i updated to 4.8.4. I had small problems , like some text has gone … but i could not find the problem . So i decided to restore from backup and then i got the fatal error i told you before.
The version of PHP on the server is 7.4.21.
What about the new update? Did you fix the problem ?
Best regards,
Viktor
