I have been having this problem for several weeks now.  Trying to reclassify a handful of deposits to a different account.  I have re-activated all inactive accounts (a bank account and an income account, specifically) that may have been associated with these transactions, and yet I keep getting this message:  SORRY.  WE WEREN'T ABLE TO MAKE THOSE CHANGES.  When I hover over the exclamation mark under the "Error" column, it says THE ACCOUNT YOU ARE TRYING TO USE HAS BEEN DELETED.  However, I have re-activated all the accounts, made them inactive again, re-activated again . . . I've even tried an incognito browser as one expert suggested.  I've cleared the cache.  No luck.  Period.

Also, while trying to fix this error, I noticed that a transaction I posted just last week (January 2022) showed up with the date in JUNE 2020.  Really?!!!

Whatever is the glitch in the program needs to be tended to, and soon.  Bookkeepers aren't able to do their jobs with this kind of performance in a program that's supposed to be "second to none."
