Please check out the server requirements below.
– You have to use PHP version 7(minimum)
– You should have proper writable permission
– CURL should be enabled in your server
Please Note: Your main server meets all of the requirements, that not mean your shared hosting also meets all of the server requirements and has all of the permission that needs to have to install the script. All shared hosting has so many limitations of permission to use a sever.
So, please try to install the script in another server that not a shared hosting with limited permission server where the server meets all of the server requirements to install the script.
Moreover, Our script has no issue. Please check out some of our client’s live website blow as a reference. They have installed and using our script on their domain.
