You should ask at the theme’s support forum, but you might have to fix it yourself. You would need to search for the exact version of the browser, because IE6 is super old but had a lot of issues. IE7 is better, but still has specific fixes to make in CSS. IE8 is still better, but has other fixes. These days, some themes support IE11, but that is the oldest they support, and that is not supported much. A lot of themes don’t support anything but the latest two versions of the modern browsers, so will not help you.
I have confirming this problem with IE11. It seems IE does not recognize the Gutenberg block ‘Media & Text.’ In these blocks the image is programmed to be wide but 25-38% of the total block. However, since IE does not seem to recognize this type of block, the image simply becomes the full width of the screen and the text follows below the image. I attempted several HTML edits but all seem to corrupt the Gutenberg block and have no effect on the page as viewed in IE. There does exist a CSS editor for the blocks within the theme; but, I have no idea what to try. Any suggestions at all? Thanks
