But yes, that was it! 🤩 Files uploaded and all error messages gone. And I was able to cleanly uninstall the calendar module. Many thanks for your help. 👍

Thank you for your reply. I have the latest version of IPB and my PHP version is 8.1. OK to download the latest calendar files but where can I find them? I have renewed my license every 6 months but only for the Forum part. I guess that's why the calendar files haven't been updated. [EDIT] Oh, I think I've got it. So I have to do a manual upgrade?

Hello everyone, I've been using the Invision solution for a long time. Back then, I bought access to the forum and calendar. Then I no longer needed the calendar module. I deactivated it and forgot about it. I wanted to uninstall it today, but what a bad idea. Now I'm getting error messages all over the place and can't access the administration area. I have an error message: And I also get messages like this in the public area of my forum. Reading the support, I can see that one way might be to delete the cache, but I don't have access to the part allowing me to do this. Any help is welcome. Thanks
