I am building a server on Ubuntu 22.04 with Apache2 - latest version. When I enable ModSecurity, I get an error message when I try to restart apache. As soon as I disable ModSecurity, the error message goes away when restarting apache and my website is back online. Any suggestions?

Have You run apachectl configtest?

Important Notice: From CRS 3.2.2, 3.3.3 and up, ModSecurity 2.9.6 or 3.0.8 (or versions with backported patches) are required due to the addition of new protections. We recommend upgrading your ModSecurity as soon as possible. If your ModSecurity is too old, your webserver will refuse to start. As a temporary measure, you can delete file rules/REQUEST-922-MULTIPART-ATTACK.conf. However, you will be missing some protections.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
