zenzoidman Posted March 21, 2022 Share Posted March 21, 2022 I recently updated my community's PHP version from 7.4 to 8.0, and ever since, I've been unable to get the software to recognize Redis. This is what I see when I go to the settings page (with my directory blacked out for privacy reasons): I've confirmed that I have Redis version 6.2.6 installed on my server, as well as the Redis PHP extension. I've also cleared my community's system cache just in case. Is there anything else that needs to be done to make the software recognize Redis?

Jim M Posted March 21, 2022 Share Posted March 21, 2022 I would suggest reviewing that the Redis PHP extension is indeed installed and being used in the directory which your Invision Community installation is in. From this screenshot, the PHP extension is not present in what PHP is passing the software so the option is not available to use it. Link to comment Share on other sites More sharing options...
zenzoidman Posted March 21, 2022 Author Share Posted March 21, 2022 (edited) Best I can tell, it is installed. Here are the results of the php -m command in the directory where my community is installed.

Randy Calvert Posted March 21, 2022 Share Posted March 21, 2022 Do you run multiple versions of PHP on the same machine? Last time I saw this happen, the CLI was returning the older version whereas the domain was on the newer version. In your ACP support section is a link to a phpinfo output. Does it show the redis module loaded? It should look like: Link to comment Share on other sites More sharing options...
zenzoidman Posted March 22, 2022 Author Share Posted March 22, 2022 Thanks for that tip, Randy. That looks like it might be what's happening here. I'll let you know if that's the solution. Randy Calvert 1 Link to comment Share on other sites More sharing options...
Solution zenzoidman Posted March 23, 2022 Author Solution Share Posted March 23, 2022 Turns out the solution was as simple as restarting our PHP server. Once we did that, Redis showed up in phpinfo and was recognized by IPS. Link to comment Share on other sites More sharing options...
Randy Calvert Posted March 23, 2022 Share Posted March 23, 2022 That would do it. Once you installed it, a reboot will cause the new version to take effect. I’m glad you were able to get to the bottom of the situation! Link to comment Share on other sites More sharing options...
