I’ll see if I can reproduce the issue. It’s hard to imagine how it could be caused by L&L’s cache, since it does not change the content. It only performs the same processing logic on page save instead of during page render. So if <p> tags are being removed, it must be happening during page render, which has the exact same processed data, with or without cache.
Well, I’ll see what I can find out. If the issue doesn’t happen on my end, then it’s likely related to Litespeed. Otherwise, maybe something to do with how ACF’s WYSIWYG field works.
I just did a little test by turning the Tangible object cache back on, and the issue came straight back. Litespeed was also running, and disabling the LiteSpeed plugin did not resolve the issue.
It’s noticeable because my CSS can’t target the <p> tag anymore:
