I tried to upgrade the PHP from 8.0 to 8.1 (with 8.2 now being available on my host server) and got a bunch of "deprecated" errors (see screenshot attached). Am I missing an update to the template? or other? If so, how do I fix this issue?
To complicate matters a bit, there are two other sites running on this same account, using Nina and Amelia – how do I find out if I also need template updates on these?
