Unable to update from 5.3.98 to 5.5.41

I’m trying to update from 5.3.98 to 5.5.41 but when I click on “Update Now” and enter my password it spins for about 30 seconds then gives the following error “FormatException: SyntaxError: Unexpected end of JSON input”

Hopefully someone can shed some light on this. It’s hosted on Ubuntu 22.04 and was installed via Ploi Marketplace.

Thanks in advance


It may help to increase your PHP memory limit.

Note: as of v5.5 the app now requires PHP 8.1.

Thanks, will look at the memory limit. The server/site is already on 8.1 for my personal projects so all good on that front

All sorted now, was the PHP memory limit causing the issue.

Glad to hear it, thanks for the update!
