Hello,

I recently moved my website from an Ionos shared hosting to an Ionos dedicated Plesk server running Ubuntu. However for some reason our website no longer wants to post data from any off the pages it use to, please see examples below:

Does anyone have an idea what the issue could be or has anyone experienced the same issue and would now how to fix it

It for sure doesn't have anything to do with Plesk. This is rather a PHP settings issue or might be linked to the Nginx proxy and its caching setting, depending on the URL that is used to receive the POST (e.g. whether it is treated as a static page or dynamic page). Without more information but "it doesn't work" (the example also only shows that there seems to be an issue, but does not show how these outputs are created and where they result from) it won't be possible to determine the cause.

So I can supply the code if required but one example is:

We have a php page called 'confirm_results.php' where an admin can confirm results submitted by managers or insert results if they're incorrect or missing, this is done via a form and then posted to another page 'approve_score.php' where it is then checked and then inserted into the database and then updates the league table as well. In our original site this worked fine and would submit without any issues, however on the new server when we submit the data via the form it sends it to the 'approve_score.php' page, but then on that page it is no longer getting that data from the form, instead it is just blank
