 * Upon plugin activation I’m getting the following error:
 * The plugin generated 2894 characters of unexpected output during activation. 
   If you notice “headers already sent” messages, problems with syndication feeds
   or other issues, try deactivating or removing this plugin.
 * and in the debug log it says:
 * WordPress database error Table ‘xxxxxx.xxxxxx_options’ doesn’t exist for query
   SHOW FULL COLUMNS FROM xxxxxx_options made by require(‘wp-blog-header.php’), 
   wp, WP->main, WP->parse_request, do_action_ref_array(‘parse_request’), WP_Hook-
   >do_action, WP_Hook->apply_filters, rest_api_loaded, WP_REST_Server->serve_request,
   WP_REST_Server->dispatch, WPS\API\Items\Products->get_products, WPS\API->handle_response,
   WPS\API->handle_response_logic, WPS\API->run_processes, call_user_func_array,
   WPS\Processing\Variants->process, WPS\Processing\Vendor_Background_Process->dispatch_items,
   WPS\Processing\Vendor_Background_Process->save, WPS\Processing\Variants->before_queue_item_save,
   WPS\DB->has_compatible_charsets, WPS\DB->has_compatible_charset, WPS\DB->get_table_charset,
   WPS\DB->get_col_info
 * What can it be?

 * Now for the why: The internet is a wonderful place full of very nice people and
   a few very bad ones. I’m sure everyone here is very nice however, by giving some
   ones keys to your house you are trusting they wont steal anything. Likewise the
   person who takes the keys is now responsible for the house FOREVER.
 * If something was to go wrong, then you the author may well legally become liable
   for damages, which they would not normally have been as their software is provided
   without warranty.

   you to repeatedly stop before escalating up to the plugins team.**
