Hi Ziaul,
With the plugin enabled you are not able to save uploaded images to joomla Atum admin template, after clicking on save, the images are not saved and the fields are blank again. I tried with the helix 2.2.3 i saw on a post, but the post was locked. Disabling helix plugin (2.2.2 or 2.2.3) allow the expected behavior when updating custom images to joomla adminitrator template. I am having several issues with the template Wayne Corp and I uploaded several screenshots (https://www.joomshaper.com/forum/question/42729) probably related to helix framework plugin like no off canvas.
I would appreciate some feedback or patched to fix that template.
Best
Johnny
