Hello,

I’m trying to upgrade my community to the latest version and after uploading the files, this is the error I’m seeing in my Admin CP:

We're sorry, but a temporary technical error has occurred which means we cannot display this site right now.
syntax error, unexpected '->' (T_OBJECT_OPERATOR)
You can try again by clicking the button below, or try again later.

I believe it has to do with the PHP version, but when I switch the server to PHP 8, the site won’t load at all.

Any ideas on how to fix this and proceed with the upgrade?

Correct - you need to switch to PHP 8.0 or 8.1, but not 8.2

Correct - because 4.5 doesn't support PHP 8.x

 

Any ideas on how to fix this and proceed with the upgrade?

Leave the ACP and instead go straight to https://domain.com/admin/upgrade to begin the upgrade.

Thanks for such a quick response, Nathan.

/admin/upgrade gives me a blank page with any PHP version, including 8.1.

 

I believe I’m having the exact same issue as this client — would appreciate it if someone from IPS could open a ticket for me.

 

/admin/upgrade gives me a blank page with any PHP version, including 8.1.

In that case, you need to ensure that your PHP 8.1 installation meets the requirements. Download the following, upload it to the root of your IPS install and run it in the browser, correcting any flagged issues (most common one is that the SQL extensions aren't enabled)

Already did this, everything is green.

If you are getting a blank page, please check your PHP logs to see what the actual error is

Hi Marc!

This is the latest error:

You need to take a look at your conf_global.php file, as something is not correct in there. Have you manually changed something in there?

This is what it looks like. I haven’t changed it in years.

This isn't using proper backticks. You can remove this line

Oh wow, thank you.

It worked!

Hi again! 

My upgrade went smoothly, but I’m getting the following errors:

Data Storage Not Working
Cache Not Working

 

The Redis option is greyed out and says “In order to use this method, the Redis extension must be installed on your server.”

I contacted my host and Redis is installed and working.

Any idea what is wrong?

 

Redis is installed and working.

That it may be, as it is a separate server software - but is the PHP extension for Redis loaded?

Go to the Support page in the ACP, click on the PHPInfo button and review what is loaded - no redis, contact your host.

Thank you for the response! Here’s what my phpinfo says:

The “Data Storage Not Working” error is now gone, but “Cache Not Working” is still there.

Finally working! Thanks everyone!
