Hi, I not only deactivated all plugins on old blog I also deleted them all from WP plugins direct... After coping new 3.8 files blog works fine, but after some time I am Blank Page screen victim. After I delete wp-include and wp-admin and copy old one blog works.. It seems blog is on heckers checking list and WP 8 has some hole..
And please advice - which version do you recommend to have to avoid problems..?
Thx a lot!
Using 3.6 IS a security risk. There aren't any known issues with 3.8 - if there were this kind of issue, we'd be seeing many people reporting similar problems. Can you reproduce the problem with ALL plugins deactivated and a default theme active? For further discussion, please start your own thread.
