I’m using an iframe as a header replacement on the home page of this site: https://gazzolocreative.net/ but it disappears when upgrading to 5.0.6. I had reported this problem previously on a different site (which will need upgrading too) and weaver was able to fix it with version 4.4.8 but it looks like it didn’t get transferred to 5.0.6. Site referenced has been restored to 4.4.8
This is indeed a bug. It was the result of making some of the Weaver Xtreme custom html fields more secure, but the code was not updated properly for all instances.
I will not release a new 5.0.7 version yet, but there is a new 184.108.40.206 “Bleeding Edge” version link at https://weavertheme.com/current-versions/ (at the bottom) that can be downloaded that fixes the issue. Eventually there will be a 5.0.7 that will include this fix and likely others.
