Guzzlehtml error following upgrade

[RebeccaParticipant]

Since I upgraded from v2.23.14.26 to v2.24.1.26, various sites on my multisite are unable to load, both on the frontend and on the backend. The error is "Uncaught Error: Call to undefined method GuzzleHttp\Utils::chooseHandler()".

What appears to be happening is that another plugin is initializing a more recent version of GuzzleHttp that does not have the method chooseHandler. This issue was also pointed out in “Still problems with very old GuzzleHTTP client” (https://updraftplus.com/forums/topic/still-problems-with-very-old-guzzlehttp-client/).

Is a fix incoming, and is there a way to work around this? I’ve tried using the option_active_plugins filter to unset UpdraftPlus in a Must Use plugin, but that didn’t work.

Hi Rebecca,

Apologies for the inconvenience caused

Yes, we already have the fix for that 3rd party library issue, it will be added to the next release of UpdraftPlus. In the meantime, to work around the issue, you can download and extract the following zip file

https://filetransfer.io/data-package/JqSCyKmq

it contains a file named class-updraftplus.php, which is the core file of the UpdraftPlus plugin. Once extracted, you will need to copy and/or move the file to the UpdraftPlus root directory (/plugins/updraftplus), it will overwrite the existing one you have in that directory.

Thanks

I tried applying the class-updraftplus.php patch to my dev install, and it did fix the problem for me
