XF 2.3 I can no longer save any RM-related permissions

[Robert9]

Hi all,

I'm facing a strange issue with the Resource Manager permissions. I can no longer save any RM-related permissions – not for users, and not for user groups. The fields show up normally in the admin UI, but any changes I make (enable/disable, etc.) simply don't get saved. Other permission groups (like general, forum, etc.) work fine.

Unfortunately, I can't say whether this is a new issue or if it's been broken for a while – I just haven't touched RM permissions in a long time.

So far I've tried:

Rebuilding permission combinations

Reinstalling the RM files (overwriting them)

Checking the xf_permission and xf_permission_interface_group tables (everything looks OK)

Clearing caches and checking for JS errors (nothing unusual)

Verifying the RM permissions exist and have the correct types and interface groups

Manually testing permissions via SQL – they work if inserted directly

Does anyone have an idea where I could look next, what might block saving specifically for the RM permission group, or how to debug this deeper?

Thanks in advance!

Your server configuration, perhaps? Do you have like anything like ModSecurity running?
Also would be worthy to check your dev console to see if there are any errors there that could give some hints.

I can no longer save any RM-related permissions.
Other permission groups (like general, forum, etc.) work fine.

I can save all other permissions, but no RM permissions.

Alright. I’ve deactivated all Ozzmodz add-ons with resource permissions.
Now I’ll check for updates and then reactivate them one by one until I find the problematic one.

I’ve updated some add-ons and deactivated others.
Now I can change Resource Manager (!) permissions for user groups, but not for individual users.
All other permissions save correctly.

Any idea which functions I should search for in the add-on directory?

I just found out that it wasn’t the permissions for the Resource Manager, but rather all permissions from a certain point in the form onwards. That was the clue – I had recently changed something in the php.ini.

The problem was caused by max_input_vars.

Thank God I figured it out. One good thing came out of it: I finally uninstalled everything that wasn’t necessary and also deleted all files from add-ons that are no longer in use.
