We just finished our 1.2.3 migration. So a downgrade is not an option. Did I get that correct, the bugfix is already in 1.2.4? When will 1.2.4 be released?
This bug is major and happened on a stable release, as it prevents from listing bug tickets here. We have some custom reports that only work once, then fail. Using another report and switching back, makes it work again, but every reload makes it fail. This is blocking the team a lot..
Best regards.
