Your website may currently be undergoing maintenance or in the testing phase and you may want to temporarily close it.
In that case, you must follow the following steps:
Go to the PrestaShop administration panel.
Then click on Preferences > Maintenance. Click on NO to deactivate the store.
To access the website administration, we must add the IP. This procedure is not recommended if you use a dynamic IP because when it changes, you will not be able to access with the old IP unless you have it enabled.
