@codecandid, thank you for reporting this.
In some hosting situations, CBQE and Testimonials don’t work together. This is despite there being a class_exists check for class Aihrus_Settings at http://plugins.svn.ww.wp.xz.cn/custom-bulkquick-edit/tags/1.5.0/includes/libraries/aihrus-framework/class-aihrus-settings.php.
While, I’m able to replicate this problem, I’ve not been able to defeat it yet. I’m still working on a fix, but not sure of the real reason why the class_exists check fails as it seems parallel processing or something what’s causing the problem.
I’m now officially tracking this issue at https://github.com/michael-cannon/custom-bulkquick-edit/issues/48.
Where are you hosting at? I’m on WP Engine.
