I have the same problem .
I tried to migrate files but seem to have lost their category and now I can’t show by category ( and I can’t find previous settings)
I’m having the same problem.
I’ve changing the content-single.php code and no changes works. I don’t use chaching system.
Thanks
It was a problem with “select{-webkit-appearance:none }” because the form don’t have this rule but there was one in my template.
I solved it by adding a rule in my custom css whit !important.
