Hey trying to use the Frontend Editor in SPP Pages view re the documentation here:

https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-3/frontend-editor

PHP v 7.3.13 SPP v 3.7.9 Template G5 Helium

All I get is an endless loop. Developer Console shows the following errors:

Uncaught SyntaxError: expected expression, got '<' 8:85 Uncaught ReferenceError: addonsJSON is not defined <anonymous> https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:61 t https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:1 <anonymous> https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:61 t https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:1 <anonymous> https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:30 t https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:1 <anonymous> https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:30 t https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:1 <anonymous> https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:1 <anonymous> https://ownermanager.com.au/components/com_sppagebuilder/assets/js/engine.js?0808dd08ad62f5774e5f045e2ce6d08b:1 engine.js:61:40198
