Thank you I am able to solve the problem by uninstalling WordPress and installing again. but for this, a new problem occurred. after a fresh installation, while I am trying to activate Xstore it is showing – “You have reached activation number limit.
According to the ThemeForest license policy, you can use 1 license for 1 project only.
Ping us along the way if you have any questions here.” Please help me regarding this matter.
