Winden + Plain Classes BUG

Hi,

on an old website I still had those plugins active:

  • WordPress 6.8.3
  • Oxygen 4.3
  • Plain Classes 1.0.14
  • Winden 1.1.9

After running WordPress and plugin updates, using Winden migration plugin and doing some manual Winden adjustments, I am now on these versions:

  • WordPress 6.9
  • Oxygen 4.95
  • Plain Classes Oxygen 1.2.3
  • Winden 2.8.3

No matter what I try, I can’t get my old plain classes to show up in Oxygen.

They are still in the JSON code, e.g.:
“classes”:[],”plain_classes”:”h1-small pt-2 sal–slide-up”}

I tried the “Migrate Button” within the Plain Classes Oxygen Plugin as well.

Is there a way to still migrate those css classes? A script, or a database query?

 

Thanks
Daniel
