While site home url is changed also customizer does not work, I managed to get there fatal error that something is wrong in file event star – class-at-theme.info.php
in row 63. I tested that row in php validator, there were no errors according to that. However, only option to get site back was to deactivate event star theme, change urls back and deactivate troubleshooting plugin I was using to test.
Also – if the site`s home url is different, also admin bar disappears when I´m in a page view. I have another site (with other themes) set up like that and there is no errors like that. Any response from author would be much appreciated!
