i made clean installation, but problem persist.
If you go to one page–> edit, there are this error and others error of page builder.
Problem are only here, rest of WordPress platform is ok. I think is a problem with old version of site builder or similir.
Can you investigate?
If i activate other base theme (like twenty fourteen or twenty fifteen), all works fine.
I write login credential in past response.
I need to modify website.
If i can’t, i must migrate to another theme.
Thanks for help.
