iam experiencing a bug on custom fields. I have a pdf-file upload for my site depending on a category.
It worked well since i used it last time (idk what version that was) but now with version 2.7.19 or 2.8.0 i can not insert a file anymore. The file browser lags to load; see attachement.
On other sites (i.e. dashboard) the file-browser works fine.
Looking forward to your help.
