Hi!
I updated a couple of my sites to Version 9.1.3 and they are now php 8.1 compliant as the ‘Atomik Agency’ theme (which is written for Version 9) seemed to have dropped in to my ‘Themes’ and I activated it. However, I have another website that I need to align with php 8.1… but can’t seem to find the free version of the ‘Atomic Agency’ theme.
Can you give more detail about what steps you followed to get to the error? Also, which line are you referencing as there are 3 errors in this screenshot.
The fopen error is because your server needs to have allow_url_fopen turned on in order to download things from the marketplace.
I’ve never attempted to download a large upgrade using the dashboard. If you have ftp access you can follow the instructions here to upload the v9 core - How to Upgrade Concrete CMS
