Hello,
We have removed some headers types in 5.0 version of our theme because they were very similar and seems you used one of the removed headers. Please, edit pages and choose the header type that suits your needs.
5.0 is the major update and we even announced the beta version of theme to allow users to test it on the dev sites before the production site update. That’s why you faced some inconvenience after update from old 4.x version to 5.x version, we improved a lot of things https://xstore.8theme.com/update-history/
Check site now and let me know if you would like to change anything?
Regards
