Hi,
I just bought and downloaded the coming soon plugin for joomla 4 , but when i install and publish the plugin i get this error:
0 - Call to undefined method Joomla\Database\Mysqli\MysqliDriver::query()
Something is not right yet for this for joomla4
please help.

Hello??? Any news about this?

Oh man... we just had to set the website ONLINE and than actived JUX plugin... it's logic... but maybe a good one to notice in the plugin?
