qooba Oh, you're on the same hosting. There you can install your own version of composer and then you use the version of PHP you want.
We have just a problem on one of the accounts on this hosting.
On the test account the extension works correctly, but on the production one unfortunately not. It serves cached pages even when the user is logged in in case the guest has visited the page before. Can you check if this happens on your forum as well?
I currently had to disable this extension and am looking for the cause of the problem.
