I have a fully patched v4.7.0 running. I switched my server from PHP 7.4 to 8.0. When I did that, there was a 500 error in the browser. When I looked at the server logs, I saw the following repeated several times:

[27-Jul-2022 15:07:10 UTC] PHP Fatal error:  Unparenthesized `a ? b : c ? d : e` is not supported. Use either `(a ? b : c) ? d : e` or `a ? b : (c ? d : e)` in /home/realtree/forums.realtree.com/public_html/system/Theme/Theme.php(885) : eval()'d code on line 525

I have another fully patched v4.7.0 running on the same server. That site had no issues when I switched to PHP 8.0. Is this some type of theme problem? I compared the Theme.php file in both sites, and they're identical.

Are you running a custom theme?  If so… try switching back to a default theme and see if the problem persists. 

It may be an issue with your theme itself. 

As Randy mentioned, check your themes and third party applications/plugins by switching to an unmodified theme and disabling third party applications/plugins.

So, I upgraded to 4.7.3 this morning and tried the switch to PHP 8.0 again. This time I'm getting a different error. Can you confirm this is related to a theme? Maybe a global template?

The PHP8 Compatibility Scanner on the support page isn't showing any issues. Any suggestions for my developer to troubleshoot this?

Yes, this shows that your theme is out of date and needs to be updated to include template changes that were introduced in newer versions.

Have a look at this guide, the second part "Comparing within the AdminCP" will be the most useful since you may not know which version your theme was originally created in.

 

Today, I reverted all my custom templates in my theme, and I'm still getting the same error. Is there any way to force it to rebuild the template_1_ad9ae6e9ced8695954ac11f917afdfac_global.php file based on the current templates?

We would need to look further into this for you, however the access details on file appear to be incorrect or missing. Could you please update these details by visiting your client area, selecting the relevant purchase, then clicking "Review/Update Access Information" under the "Stored Access Information" section. 

We look forward to further assisting you. 

 

I've updated the Access Information

Could you please clarify where you're encountering this error? When viewing your community, everything seems OK. 

It is also noting that your Benelli theme is still customized.

I think we've resolved the issue. We created a new theme and applied our customizations to the templates once more. Seems to be working.

Glad to hear you resolved your issues.

Im not sure I understand what question you are asking there, as what you quoted is what they did there. They created a new theme in the admin CP, then reapplied any customisations they had.

To clarify, this will have resolved the issue, as there will have been changes in the theme that were breaking changes in PHP8

Same type of issues on my side. I suspect the new version of IPB that hides some css files is not showing a few we edited.  I may go the same route as you to start clean.

As mentioned on the other ticket you have. We would need to know which theme, and we can take a look for you

I have resolved my issued by disabling one of the plugins I had. Now I need to find a replacement. It was called "Hide Content Until User Replies" 

Glad to hear you found what was causing your problem there, and hope you find what you need in terms of replacement
