The smaller chunks worked. Thanks!
Done & cleared the cache. The sidebar ad now shows “Advertisement” but none of the ads are showing.
I’m assuming the other errors are Amazon, so I’ll get in touch with them. One error at a time 🙂
Looks like this was my fault. I have been playing with settings on the other blocks & trying out features I’m not currently using. Disabling them fixed the issue. Sorry to bother you & thanks for the quick response though 🙂
It’s enabled and I have turned off caching.
