I’ve updated Sydney Toolbox to version 1.03 but now it can’t be activated with this warning:
Parse error: syntax error, unexpected ‘[’ in /home/user/domains/domain.com/public_html/wp-content/plugins/sydney-toolbox/sydney-toolbox.php on line 100
I’ve deactivated all the other plugins but it gives still problems.
I have WordPress 4.9.6. and not so many fancy things. Is there anything wrong with this version or what can I try to fix this?
