Upgraded 3.3.4 to 3.3.8 - first screen shows only, blank screen for response

the upgrade went smoothly without any errors seen.
I can login, i can select from the menu, i will always get the first screen of the selection. So for example, if i add a subscriber, i get the first screen enter email address, press enter. i don’t get the next screen which would show you everything. i get a blank screen, i then need to backup within the firefox, explorer…etc. I can search and find the email added, i then can edit to complete.

I am trying to send a campaign, i can compose and save, but i can’t go to step 2.

any ideas

Check the phpList log (System->Log of events), and enable PHP error reporting and then check your web server error log. A white screen implies a fatal PHP error.

Sam, what version of PHP do i need to be running? I hosting package is currently at 5.6 & 7.0 are available.
