PHP Fatal error : Cannot access offset of type string on string /usr/local/www/status_interfaces.php:137

[stephenw10]

It's in the config file in /cf/conf/config.xml:

	<switches>
		<switch>
			<device>/dev/etherswitch0</device>
			<vlanmode>PORT</vlanmode>
==>			<vlangroups></vlangroups>
			<swports>
				<swport>
					<port>1</port>
					<state><![CDATA[forwarding]]></state>
				</swport>

Removing that line and rebooting should be sufficient.

@stephenw10 Thanks! Will try that asap. When trying just now I realized that sudo was missing so went into packages to verify and - none of my packages are there. In fact, no packages are available for install either... Sorry for the hassle, am a bit eager to try 23.01 again after this...

It seems it tries to get packages for 23.01 even though I am on 22.05 now... Uh.. What should I do, really? Fix this before flashing or ?

[stephenw10]

Upgrades for aarch64 (1100 and 2100) are disabled temporarily whist we fix the upgrade bug hitting systems with older installs. https://redmine.pfsense.org/issues/13967

Should be back soon. We have a good handle on what's happening there now.

So if you want to test that now you can install 23.01 clean and import the config with that line removed.

Hi, sorry for being so quiet, but have struggled with the device all evening.. :/ I had somehow managed to turn off some DNS rules I needed and never thought of checking. I went ahead and did a clean install of 23.01 and imported my saved config. After removing the line you suggested, the interface issue was gone. But instead checking the 'System / Update / branch' it was empty, and I had no packages available to install. So am back on 22.05 again. Getting a little tired jumping back and forth, always something I miss that complicates things a bit. Come to think of it, when logging in to 23.01 for the first time it gave a yellow banner that it was loading packages... But if my DNS was borked, that may well explain why it failed and none were available. But still, should the branch be empty?

Nevertheless, I'm happy to hear you are homing in on the issues with the 1100 & 2100.

Hello again,

@stephenw10 Do you need more information to resolve the issue https://redmine.pfsense.org/issues/13981 ? Is it planned to be resolved soon ? Thank you

Stubborn as I am, I did this once more yesterday, and had great result this time. I haven't found anything malfunctioning this time, other than the restored backup contains the tags that needs to be removed after upgrade/restore (or by modifying the xml file prior restoring)

It seems to be planned for the May release; https://redmine.pfsense.org/versions/71

[stephenw10]

It's marked as 23.05 for the target but it will likely be fixed much sooner than that and when that happens it can be added via the system patches package.

@jimp This patch has been applied successfully on my SG-3100. I can look the interfaces page again without a fatal error, thank you !

Hi, I got the same PHP python reference error upgrading to 23.01 on SG-3100. I looked at the config file I was successfully using under 22.05 and couldn't find the exact line above you note that should be deleted.

23.01-RELEASE (arm)

built on Fri Feb 10 20:06:58 UTC 2023
FreeBSD 14.0-CURRENT

The system is on the latest version.
Version information updated at Mon Apr 17 17:29:10 EDT 2023

Here is what I found in the config file - can you advise whether I should delete one or more lines in this file?
Thanks....

<switches>
<switch>
<device>/dev/etherswitch0</device>
<vlanmode>DOT1Q</vlanmode>
<vlangroups>
<vlangroup>
<vgroup>1</vgroup>
<vlanid>4081</vlanid>
<descr><![CDATA[Display port 1]]></descr>
<members>1 5t</members>

[stephenw10]

You have at least 1 vlan group defined so whatever you're hitting it's not the same bug.
Are you seeing exactly the same php error?
Can we see your complete switches section from the config?

Steve, I didn't save the crash or php files, thinking they would be available inside the pfsense GUI as a selection, so don't have. But the error had to do with loss of a string reference and might have been in the PFBlockerNG application. Sorry to be vague. Although I configured the gateway and vLANS myself, I am still pretty much a newbie at this stuff.

I have been running this config of pfSense for 2+ years and didn't have any problems with three releases of pFSense until this one. Despite the fatal error, things seem to be working, but unless there maybe a fix in the near term, I will revert to the previous release of pfsense.

The file below is a cutout of the switches section of the config file I was using at the time of the system upgrade.

Thanks so much for your assistance.

Steve,
Couldn't access the Crash report.

here are the contents of the PHP file:

Ah that's a completely different error. But you can see that's in the deinstall script that runs during the upgrade. It's almost certainly due to the php change at that point and would not be present after upgrading. If you clear the error(s) does it return?

Is that switch config actually from your file? It's invalid xml because there are missing ]s from several lines. Fort example:
<descr><![CDATA[test_net]></descr>
Should be
<descr><![CDATA[test_net]]></descr>

@stephenw10
Steve,
Thanks for your review of the error message and my misunderstanding of what happened.. PFsense and PFBlocker seem to be working fine.

I cleared the message from pfsense and will see if it recurs.

The missing "]" s was simply a transcription error on my part in extracting from the config file.

I confess I don't understand PHP, but wonder why this 'fatal error' never occurred in previous upgrades of PFsense. Could it be that there was a patch to PFblockerNG that occurred since the version I had, and perhaps the fatal error occurred because PFsense had to remove the version previously installed??

Bill

[stephenw10]

It didn't happen in previous releases because php didn't change major versions.

The same thing (or similar) did happen when we moved from php5 to php7 a few years ago. We mitigated numerous php issues in testing but with a major version change like that there were always going to be some we didn't find.
