Magento 2 extension error: Blank Page, Site down

For some reasons, the installation process may cause your store stop working, blank page or site down.

  • If you backed-up your store before processing installation, restore the backed-up state.
  • If you don’t have the backup. The following step will help disable our extension.

Step 1: Disable extension in backend

disable extension

Step 2: Disable via command line

If step 1 doesn’t work. Then you can disable by command lines. Please notice that this is all about your store, you should know how to run command lines, this has nothing to do with our extensions or any extensions in general. If you see errors such as “cannot write”, “permission denied”, “php is not command”, you should contact your developers or your host provider.

Usually, you should run the following commands to disable an extension:

In this case, we will disable Mageplaza_Osc

php bin/magento module:status  ##to list all installed modules
php bin/magento module:disable Mageplaza_Osc 
php bin/magento cache:flush
php bin/magento cache:clean

If needed, you can run module:status again to see if the extension is actually disabled.

If you have other cache services such as Redis, Varnish, please also flush cache of those services. Deploy your store if needed.
