Something seems to have gone wrong with my theme as every time I try to make a customisation change I get this message:
Unable to save due to 1 invalid setting
There are no details about what this is, it just won’t let me do anything. I’m using the Wordsmith theme and recently installed Smush and Hummingbird to try to speed my site up. Would they cause any problems?
When I turn Gutenberg off, it’s fine. When I turn it back on again, I get the problem. I haven’t tried it with all of the plugins off yet, I’ll try that next. Thanks
