Since that is a commercial plugin, we ask that you please go to their official support channel, so you can get support from the people who know it best.

Forum volunteers are also not given access to commercial products, so they would not know why it is not working properly. Other community members who may have faced your issue might be able to help you but your best bet is your product’s developer. Keep in mind we encourage you to use the official support venues, as it allows the developers to be aware of issues with their code and gives back to the community in a more robust way.
Thank you for your reply mate.
BTW you can access the plugin here https://ww.wp.xz.cn/plugins/gallery-master/
Their free/trial plugin also works fine on other website but not on my website that I have mentioned above.
In that case, I recommend asking at https://ww.wp.xz.cn/support/plugin/gallery-master#postform so the plugin’s developers and support community can help you with this.
Posted for the help in support section. Let’s see if I could find solution in a short time there.
Thx mate.
