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.

Hi Brian,

I was adding the Stylesheet parser plugin to Wyvern module. From that moment on I’m not able to save the Wyvern module settings anymore. When I hit save I’m getting a blank screen with: Disallowed Key characters.

The entry that uses Wyvern gives a blind area where normally the content Wyvern field is displayed.

I re-installed, CK editor, Wyvern but the issue stays!

Screen prints from the module set-up and an entry (with the failure messages) are attached

Problem solved. It appeared not to be the StylesheetParser causing the issue. The issue appeared because I activated the “button” in the Wyvern config file. This caused Wyvern to hang.

I changed the fields from Wyvern -> Rich text. Deinstalled Wyvern and reinstalled it again. Changed fields back to Wyvern, adjusted the module settings and everything was back up and running smoothly.

Thanx for the great support!
