I turned debugging on before I searched/posted for help
Fatal error: memory size - various files depending if I'm trying to install or import.
Now, when I go to create a new course from back-up, it gets to the last screen and goes blank (except for the error messages - it says it doesn't want to add the Paypal info, then also gives the "Fatal error: memory size" - EXCEPT it does add that new course.)
(for the record, it has never added the paypal info automatically - no matter what/when; so now I see it was a minor error and perhaps it was supposed to be adding all along - but that does not seem to be what is breaking anything)
I have done no updates, adding mods, etc since this past October when I last tried to restoring from back-ups. NOTHING has changed on my end, except the size of the back-ups.
