I tried to log in to your site so that I could see the problems for myself, and maybe take a copy for testing locally, but the credentials you provided don't work.
Let me set another private reply up, if you could please double-check them and update. (I don't need FTP access.)
I managed to get site credentials from Minesh, and I visited the problem page.
Except, I couldn't see any problems.
In the two screenshots you can see me editing the existing image field where the options for the dynamic source appear in the sidebar as expected, and me inserting a heading block which has the option to use a dynamic source in the sidebar.
(You can only specify dynamic sources for Toolset Blocks, not the built-in WordPress image and header blocks.)
Could you try clearing your browser cache and performing a hard reload?
Hi, I was using Toolset blocks. I don't know what happened. My cache was cleared yesterday, and I still had the same issue. It looks completely different today.
I'm having lots of issues with the problem Minesh is helping me with. I can't get the ranges to work correctly, and I need this function to work on Monday. Your weekend is coming. Is there someone in my timezone who can help me today? Very difficult to wait a day for a response.
