Installed on ZC 1.5.3. Uploaded all files and admin does not load then removed file from admin/include/auto_loaders and admin load.
See Testimonial Manager below Tools and Configuration but TM below Configuration does not have any fields or options to edit it load blank page?
Side box is appearing in layout controller and is on but on live site it shows "WARNING: An Error occurred, please refresh the page and try again." instead of testimonials and also footer does not appear. When I delete /includes/modules/sideboxes/template/testimonials_manager.php footer does appear.
Can you please assist how I can fix both of these issues?

Thank you!
