I’ve just upgrade a site from v1.6.8 to v1.7 and have a completely blank screen for both the site and the cpanel. Running the upgrade required clicking a number of times before 1.6.9 went to 1.7.
I have a few hours US time before the site needs to be back up, otherwise the site owner will start losing sales and be an extremely unhappy camper.
Update: Went in and disabled extensions in the config file and now the site loads. I’ll figure this out for myself and report back if anything applies generally.
