General permissions gives fatal error with PHP8.1

[~Souza~]

I have Light Portal installed and that requires at least PHP8.1. But in PHP8.1 (or 8.0) I can't load general permissions. Seems to be the only one not loading. The error I get is:

Fatal error: Uncaught TypeError: Unsupported operand types: string + string in (website)/forum/Sources/ManagePermissions.php:302 Stack trace: #0
(website)/forum/Sources/Subs.php(6068): PermissionIndex() #1
(website)/forum/Sources/ManagePermissions.php(77): call_helper('PermissionIndex') #2
(website)/forum/Sources/Admin.php(499): ModifyPermissions() #3
(website)m/forum/index.php(196): AdminMain() #4 {main} thrown in
(website)/forum/Sources/ManagePermissions.php on line 302

Hope someone knows how to solve it!

Can you uninstall the portal and the other custom mods and see if the error will go away?

what OTHER mods do you have?   Because SMF 2.1.x supports php 8.1 without error AFAIK

I uninstalled all mods, did a clean install and still it's not working. Only when I change back to PHP7.4 will it work again.

Then you have something seriously misconfigured....

Ya think...? It would be helpful to know WHAT is misconfigured. My board is old, database started in 2009 as a phpbb2 forum, was converted to smf around 2011, always updated and now recently upgraded to 2.1.4. Somewhere something is not right, I am fully aware it's a misconfiguration, but if I knew more than that I wouldn't have asked for help. If I at least would have a hint on where to find the problem I would probably be able to figure it out.

p.s. in between have had a gazillion mods, have imported stuff in fresh databases etc. Forum is working fine on 7.4 so I just installed TinyPortal instead of light portal for now. Maybe when 2.1.5 comes it will fix the issue somehow.

Can you attach your Sources/ManagePermissions.php

[~Souza~]

Sure, here you go!

First off, when you are asking for support it would help if you tone down the sarcasm and the attitude. Kindred is trying to help you.

According to the info that you provided us, that error is caused due to php 8.1. incompability. As mentioned above, Smf 2.1.4 is fully compatible with php 8.1., so that error is most likely caused by a mod that is not compatible with php 8.1. But without having an actual look in the environment where the error is happening, all we can do is make an educated guess.

That being said, you claimed that you did a clean install and the error is still happening. That's just not possible. So that makes me think that the clean install that you did was not done properly. Can you tell us how you did the clean install?

To elaborate a little further on the error, 2 vars/strings or whatever are being concatenated together with the + operator, which is depricated. For this error to go away, a valid concatenation operator should be used instead, such as the dot one (.) for example.

Is that hint enough for you?
