I am on JCE 2.7.17 with SP Page Builder 3.6.2 and template Helix Ultimate 1.1.1. (all latest versions).
And when I am editing through the frontend of my template in the SPPB "Text Block" add-on, and I try to add an article link by using the article search feature in JCE, I see this error,
"The server returned an invalid JSON response"
But the JCE article search function works fine through Joomla Core Article Editor backend.
The only way to add a link through Helix/SPPB frontend is to use the JCE tree menu article finder. Which creates a different link not ideal for our site.
Could you please advise?
I can provider backend credentials as well if needed.
I have reached out to SP Page Builder/ Helix Ultimate team as well and they told me to ask JCE Developer.
Thanks
