I am using 9.4 and the Coelesce theme. I am new to this.
While messing around with the logo module I managed to reduce the height of the banner that goes across the top. This causes the logo module to overlap the left side modules and the top of the page below it. Trying different themes does not work and in some cases causes it to get worse.
I suspect that it can be change in Look & Feel/Customization and change a code, but I really don't know.
Please help and thanks,
