I am using the most recent free version, 1.5.5 updated 28 days ago. I have ten licenses for Pro, but this site does not need any yet, so I am currently saving them for later projects.
The error is discovered by the JQuery Migrate Helper plugin for WP 5.5 immediately in the backend, so it should be easy to replicate.
I actually changed the code myself already, but updates overwrite the change. The script common-script.min.js from your assets directory uses the “ready” event twice. The first time right at the beginning:
jQuery(document).ready(function(e)
Replace this with: jQuery(function(e)
Then, later (quoting some more surrounding code):
jQuery.fn.parallax&&e(document).ready(function(){e(".qubely-row-parallax").each(function(){e(this).parallax("center",.4)})}),e(document).on("ready",function(){e(".qubely-block-pie-progress")
Correct:
jQuery.fn.parallax&&e(function(){e(".qubely-row-parallax").each(function(){e(this).parallax("center",.4)})}),e(function(){e(".qubely-block-pie-progress")
At least I suppose that this doesn’t break the functionality, I didn’t notice anything. It does solve the problem and no further error is displayed.
