Hope you are well. And sorry for the inconvenience. if possible, can you please, give your temporary wp-admin login details in a private reply for checking the issue?
After more investigation we think it is a conflict between the updates with this plugin and the memberpress plugin we are using. Currently transferring all downloads over to the memberpress download manager as this addon is integrated to memberpress. We have 176 files to transfer over! No further investigation on your end on our behalf is required, but thank you for your prompt response.
