Hey,
here is a Problem of mine,
everytime i try to open the Custom OPT out Tab , it shows me this Error.

I tried Clearing the OP Cache and restarting my Webserver but nothing fixed it.

Key "custom_css" for array with keys "idsite, name, main_url, ts_created, ecommerce, sitesearch, sitesearch_keyword_parameters, sitesearch_category_parameters, timezone, currency, exclude_unknown_urls, excluded_ips, excluded_parameters, excluded_user_agents, group, type, keep_url_fragment, timezone_name, currency_name, alias_urls" does not exist. in /html/matomo/plugins/CustomOptOut/templates/index.twig 38 using PHP 7.0.29

It looks like your SQL Tables has not been updated. Can you try to reinstall the plugin?
