| | Attempt # ???
I've just reset everything, and set the entire photopost folder and subs to 777 for this attempt. Now I get the following error while attempting to do the 5.0 to 5.1 upgrade:
"We're sorry, but the system experienced an unrecoverable error. Please try again later."
The other errors about the unlinking have disappeared to be replaced by this. Does this help narrow it down?
