All add-ons currently require PHP 7.4 or greater.

On July 4th 2024 PHP 8.2 will be the new minimum requirement for all add-ons. Expect any add-on released after that date to require 8.2 or greater. Some releases may not immediately take advantage of 8.x specific features in PHP, which means you might, be able to continue using new releases in PHP 7.4, however, if you experience an error the first thing you should do is update to PHP 8.2 then create a support ticket if the error persists.

Publisher does not support the Fluid field type. Please do not contact asking when support will be available.

I was following the installation instructions.
Clicked to proceed to “step 2” and migrate.
Now it says “Finish upgrade to Publisher 3.0 ... Error ... The action you have requested is invalid.” (see screenshot)
If I try to do anything in my EE control panel, it simply shows the page in the screenshot.

PHP version 7.3.9

Hi there. I don’t support EE5 anymore. I just realized I had not updated this for the Publisher add-on in the docs or on EE’s site anywhere, my apologies. If you’d like a refund I can do that. I announced the EE6+ only support several months ago on Twitter. You’re free to use it in 5 if it works, but I can’t offer support going forward.

With that said, I’ll try to help with this install issue though. You’ll need to inspect that page b/c it’s an iframe, and let me know what the URL it’s trying to load is. It’s probably a ?ACT=[int] url, in which case you should see a corresponding ID in the exp_actions table. Providing screenshots of both of these would help.

Sounds like you figured it out. Mind sharing what you found in case this affects someone else or if it’s something I can fix or prevent from happening?

The problem was that I had the wrong “Default base URL”. I had it set to the URL for my live site, but I was trying to install Publisher on my dev site. This caused the error I described and then later I couldn’t even access the control panel. Firefox said “The page isn’t redirecting properly”. I had to restore the entire database to an earlier state, change the base URL to that of my dev site and then install Publisher again.
