I used the name of the file already in the code, landing4.jpg, so it has been in the custom.css file as demonstrated in the screenshot I sent.
This is not a section. When I opened a ticket some time back, I was given the code to add to the custom.css file through the template configuration screen. I was told this is not a section.
But I changed this code without any problems not too long ago, perhaps a week or two ago without any of these problems, and this was after the migration of the site to J4. It worked fine until the Sheriff asked me to use a different image which included the lady jail administrator, which is there now. I would have named it landing5.jpg except for the issues explained in this ticket.
I am unable to save any code in custom.css when using the template styles. Save is not working on the popup screen that shows the contents of the custom.css, and Save is not working when I try to do a Save & Close on the template screen.
So to get the image up as soon as possible, in spite of the Save issue, I named the new image the same as in the custom.css file currently. Is this what you needed to know? I've attached a screenshot for clarity.
