Hi all, having issues with my Magento 2.1.7 store. I was updating some of the categories, but when I went to delete a category, a string of errors broke out. I can't even log into the admin. Every time I try to compile the code in the Ubunto terminal, I get this error:
We're sorry, an error occurred. Try clearing the cache and code generation directories. By default, they are: var/cache, var/di, var/generation, and var/page_cache.
[Zend_Db_Adapter_Exception] SQLSTATE[HY000]  Server sent charset unknown to the client. Please, r eport to the developers
[PDOException] SQLSTATE[HY000]  Server sent charset unknown to the client. Please, r eport to the developers
[Exception] Warning: PDO::__construct(): Server sent charset (255) unknown to the clien t. Please, report to the developers in /var/www/html/free-parking/vendor/ma gento/zendframework1/library/Zend/Db/Adapter/Pdo/Abstract.php on line 129
And every time I try to clear the cache in the terminal, I get this error,
[InvalidArgumentException] There are no commands defined in the "cache" namespace.
I tried deleting the cache folders in the var folder, but the same result. I am at a complete loss.
