Hi,
all plugins are up to date.
I explain you this issues step by step with screenshots.
1. Im add a button in backend editor of WPb Page Builder (for example in Static Block) and want to add a link.
2. A lightbox open with the link options.
3. After click the “set link” button the system displays me the message:
“please confirm that you leave the current page …”
4. I accept this message and after the reload im in the blog overview panel.
Before the update of wordpress i can add links to buttons without any issues
Regards
