Just updated to 2.2.2 via command line and now getting an internal server error when trying to access my store.
I have cleared and flushed the cache, run the upgrade, compile, static content deployment, and reindexed. Internal Server Error persists. What next?
Since Internal Server Error is, normally, an error 500, can you check your webserver error log to see if htere is a clue about the problem?
Please check maintenance.flag file under var folder.
If its found than remove it.
