I didnt say cache issue – I said js issue… clearing the js cache was a check that you did not have a stale js cache after the update since most javascript has been updated in last few releases… and I asked if you were using the combined js cache (which you may not have been)…
two other people have reported this since 5.7 release? where?
and your site is throwing js errors (you can see in browser console)… the js errors stop other js from running – like the math js from updating the button to allow saving…
in this case, it looks like some js script called minit is messing up… it appears to be trying to concatenate/minify js on the site… but it seems not working right… alot of those type script struggle when js has already been minified and/or concatenated – like our scripts are…
is that new? not sure how it could have worked before but certainly seen stranger things… 😉
any way to disable temporarily and try again? or tell if to ignore the forum scripts?
