@skandha Well, I really don’t know if any plugins I have installed were involved, other than Wordfence (based on the stack trace above).
I can certainly disable all plugins but since I won’t be updating the theme, I don’t see how that would make any difference. In any event, given the stack trace above, the theme developers should be able to look at the code, see if the message above is applicable, and make whatever changes are deemed appropriate.
I think the important information here is we’re running in a PHP 8 environment. I don’t know if that would have any impact on how the theme update needs to be performed.
So far, the site appears to be working well, with the upgraded theme in place.
Thanks!
