hi dave, thank for your reply, then i try to tell you chronologicaly so maybe it can be easier to make conclusion.
(i) i run 2 site which are using different (premium) themes from the same vendor.
(ii) 1st site running without pagebuilder (widget only), 2nd site with pagebuilder.
(iii) Setting, plugin installed almost the same.
(iv) setting of caching plugin is exactly same.
(v) all my two site showing the same strange script like above.
(vi) i change the themes of the two site to twenty-twenty.
(vii) my 1st site keep running with twenty-twenty until now and still looking good.
(viii) but my 2nd i revert it to use previous theme so it have fresh folder instalation.
(ix) unfortunately even it have fresh instalation but the strange script like coming back again.
since the caching plugin and the setting is the same so i’m not conclude this is a part of optimization of the site. i more to point problem coming from my theme.
p.s.
this is not support question and but i would like to send the complete script
