XF 2.2 No admin control panel access

[VLEPSC]

This is what shows up. Any advice is appreciated.

Which version of PHP is running?

 

[VLEPSC]

8.1.16

 

[Paul B]

Has the PHP version recently changed?

What version of XF are you running?

Are you able to downgrade PHP to 8.0 or 7.4?

 

[VLEPSC]

I can check with the host about a PHP downgrade.
How can I check XF version? can't get into Admin CP

 

[Paul B]

According to /install you're running 2.2.13.

If this issue started without making any changes then it has to be something server side, such as the PHP version.

Deprecation errors should only be triggered with debug mode enabled, so it's worth trying to disable that if you have it enabled. Otherwise you might try to enable the intl PHP extension if it is disabled, or disable it if it is enabled. We don't pass any explicit flags to idn_to_ascii, and our polyfill should set the default appropriately so it's a bit puzzling why this would occur.

Thank you. We deleted some things from the server today regarding an old Word Press site, but it was located in a different directory. Coincidence? We did submit a support ticket to XF, as I forgot we had paid for support.

I was able to disable debug in config.php and now I have admin panel access.

Brogan, it looks like PHP 7.3 is what the current version is. I do have the ability to move to 7.4

 

[Jeremy P]

Ah, it looks like this would only happen on PHP 7.2/7.3 with debug mode enabled. The default variant was deprecated in PHP 7.2 but not changed until PHP 7.4. I'll make adjustments to use the new default explicitly in future versions.

Should I upgrade to 7.4?

 

[Jeremy P]

You should always use the latest PHP version that the software you are using is compatible with (including any add-ons and non-XF software where applicable). We recommend PHP 8.0 at the time of writing.

 

[VLEPSC]

Ok, my host only offers up to 7.4 right now. I'm at 7.3 currently

Only up to 7.4? Time to change hosts then I guess, because php 7.4 is already EOL since December last year. A host should at least have PHP version 8.0 available and if possible 8.1 too.

 

[VLEPSC]

8.0 showed up as an option after upgrading from 7.3 to 7.4. When I installed 8.0 I lost site access and had to revert to 7.4. Does the upgrade take awhile? Maybe that was why as it could have been updating.

 

[Black Tiger]

Which upgrade do you mean, php or xenforo?
Depends on the version of Xenforo and speed of the hosting. I would use PHP 7.4 then upgrade Xenforo to the latest version, remember to update eventual addons too.
When all is done, you should have no problem switching to php 8.0 as Xenforo does support php 8.0.
