There should be an option to permenantly hide the upgrade notice. I was happy with my site, the way it was running, it's peformance etc. It was doing what we needed it to do - now it isn't. That isn't progress. I ignored the message for over a week, then came an email urging me to upgrade. That is nagging! I went CiC because I wanted a working forum, this is just aggravation I don't want or need - now the 3rd party party add-ons we need and our users expect are gone, either leading to a poorer forum or a load more work and expense, it's not what I need right now.
The upgrade process told me some add-ons were incompatible and would be disabled. At no point was I informed that upgrading would break the forum requiring intervention from Tech Support! At the last upgrade the process disabled our 'sort by first letter of topic' add-on, but the upgrade did finish. I consulted the author who said it WAS compatible, I reabled it without issue and it's worked since.
Sorry, but if this is to be a monthly occurance then CiC ISN'T the simple solution to our problems I wanted and I will need to seek a solution elsewhere 😞
