Yup, that JS error has gone now thank you fixing.
We’re still facing the two DB/PHP warnings as below which you said not to worry about, will those be fixed also?
Function wpdb::prepare was called incorrectly. The query argument of wpdb::prepare() must have a placeholder.
Are you planning to fix in the next week or so?
If the answer is no I will have to switch to some other cache plugin [ and I don’t want to, because I love Zencache 😉 ]
