Hello, I have Joomla 4.0.4 and Php 7.4.7 and newest Sourcerer 9.0.2 plugin enabled. The Sourcerer button shows up above the article text in the TinyMCE menu but when I click on the button to insert my php script the modal displays a sad paper face with the text refused to connect. I am not sure what to do at this point as everything else shows it is working except inserting php.
