Unstable after upgrade to 2.2.18

[musicscore]

Hey there.

After upgrading to 2.2.18 three of my website looks unstable.
After some time suddenly I have to clear the cache to get the website up-and-running.
I even sometime have to copy the corefiles to the server again (looks like one of the files is damaged) otherwise I receive a error 500.
At first I thought it was the menu manager but by replacing this by navigator on one of the sites did not solve the problem.

Does someone have any tip.

I still running php 7.4. Do I need to upgrade to php 8.x ?

Please help.

Are all the three websites located on the same webhosting provider?
Did you transfer the files using "binary" or "ascii" as FTP transfer method?`

Why not go the full step and upgrade to 2.2.20 and use PHP 8.x directly? Maybe that will do the trick?

Thank you for your response/answer /tips.

Are all the three websites located on the same webhosting provider?
Yes, But because of this problem I Transfered all my websites to a new hoster because I expected the problem was caused by the hoster. Same problem here.

Did you transfer the files using "binary" or "ascii" as FTP transfer method?`
Not shure. I used the method I always used (Using CMSMS now almost 20 years)

Why not go the full step and upgrade to 2.2.20 and use PHP 8.x directly? Maybe that will do the trick?
I will try. Did not update to 2.2.20 because of the fact that the site were still using menu-manager
Menu-manager not support by 2.2.20

To my understanding Menu-Manager will still exist in 2.2.20, if it was present previously, but it won't get any further updates in regards to PHP8.x

But before trying that, a backup is advisable

In the log I find this error message a lot :

The warning you can ignore, but the mysqli error usually indicates that the mysqli extension isn't loaded. The fact that the site works sometimes is odd in this case though, it's as if the extension is shutting down periodically. It seems like a hosting issue, but I imagine switching PHP versions (migrate from MenuManager then go to PHP 8.1) will probably solve it too.
