Problem with backoffice after installation (PS 8.2.1)

[Shab Souri]

Hi

I have many error with lines, which I couldn't find solution to solve this issue. 

I hope anyone can help me to fix it.

Hello,

This specific error is related to the fact that your PrestaShop version is not compatible with PHP 8.2 as shown here.

Starting with PHP 8.2, setting properties dynamically results in a warning. 

Downgrading to PHP 8.1 should fix all of these errors.

After I downgraded to PHP 8.1, it happened to worse. 

First it happened, when it said ''PHP is already started'', then it came like ''Notice: tempnam(): file created in the system's temporary directory''

Hello,

From what I can see in other topics / GitHub issues, this error relates to incorrect permissions to the var directory or to the fact that you might have reached the file limit supported by the hosting server.

You should check some of them: here, here, here or here

Also, you should not share screenshots that showcase the admin link in them, for security reasons. You should change that URL (the adminxxxxx part).

After I downgraded and worked fine, it happened somethings wrong like add any new image, and I can't fix it.

Hello @Andrei H

I didn't hear anything from you yet after I attached the screenshot.

Hello,

The error is pretty much self explanatory. Your php.ini seems to be missing some configurations. You should reach out to your hosting provider and ask the to configure the php.ini for PHP 8.1 similarly to how they configured it for PHP 8.2

Also, this thread on the forum might be helpful too.
