I just recently purchased this template and I am experiencing the same issue mentioned above.I have attempted to follow the instructions provided. I have changed my PHP settings to 7.4. I tried finding the htaccess file and it doesn’t exist. Searched for the PHP.ini file and I was unable to find it. I changed the access settings for the wp-content folder to “777” I attempted to locate the demo content files in the archive you have downloaded from Themeforest. None of these instructions have worked. I have contacted my provider and their is nothing wrong on their end. Please advise the next steps or provide me with a refund.
