seems like the 4.0.4 version gives a blank page on J4...i have a relatively clean site with no extra addons. 4.0.3 works, soon as 4.0.4 installed,. pagebuilder gives a blank page in the back end. have cleared cache, rebuilt db etc...all of usual things...removed and downloaded 4.0.4 with same outcome. installed 4.0.3 and all works again.

whilst im on here...is there a way not to use front end editing with the new version ?
