First of all, thanks for the help. I had already looked in the Livewire documentation, I mean even in the linked article. My main problem is that the message does not disappear by reloading the page.
If a user has logged in to the website about 2 - 3 hours ago and then some action is to be performed by a Livewire component, the said message appears that the page would have expired.
Immediately after logging in, everything still works as it should, but after a few hours the error message appears. Reloading the website doesn't help either, the message that the page has expired keeps coming up. If I then log out and reload the page, the Livewire components work permanently. As soon as I log on again, however, after an estimated 2 - 3 hours, the error message appears again when I want to use a Livewire component, no matter how often I reload the page.
As an example, I have programmed a listing with Livewire that includes pagination. When the page is loaded for the first time, the first page is of course always displayed. If you then click on the link for another page (e.g. page 2 of the listing), the error message appears that the page has expired. If I then click OK on the message box, the page reloads and page 1 is displayed again. If I then click on the link again for another page (e.g. page 2 of the listing again), the error message appears again and if I click on OK again, everything reloads again and you are back on page 1, etc.
Maybe there is something wrong with the deployment hash, but then the question arises why the problem only occurs when a user has been logged on to the website for a few hours. The user session itself does not seem to have expired, because in web pages of my project that do not use Livewire, the user login is still recognised and processed by Laravel without any problems.
