Greetings CiviCRM Community, I am in need of rebuilding our organization CiviCRM DB. We are getting some odd issues when trying to create activities in CiviCRM. When I traced the error I got the following message below. I'm think we need to rebuild our CiviDB Schema since we have done a few upgrades over the last few months. I wanted to know if there is an updated process for rebuilding the CiviCRM schema. When looking at the documentation on the wiki site it states that this documentation have been archived and the new site does not include the process. Please advise on what we should do.
