Thanks Eric,
Unfortunately this is a live site issue, so using Developer Mode isn’t an option.
In the end, we switched off CCSS and async loading in LSCache which removes the issue – this impacts our performance scores a little, but not enough for us to worry about.
We were assuming there was some interference between Sucuri and LSCache, but honestly we don’t know – I’m just aware that having multiple solutions caching can often cause issues.
We’ll be testing LSCache 4 shortly, so may try switching these options back on to see if anything’s changed.
Really appreciate your response, and if there’s anything concrete we find out on this I’ll post back,
Andrew
