I maintain a non-profit wordpress site for a relative. Recently, they have not been able to login to post. I tried logging on as admin and get a 404 for wp-admin.php. I searched and tried a number of "solutions", such as disabling the theme, deleting .htaccess, modiying .htaccess, adding the site url to wp-config.php, and so on. Absolutely nothing is working. I also cannot access phpmyadmin - I get the following error: Parse error: syntax error, unexpected '[' in \phpMyAdmin\index.php on line 60
Line 60 is as follows: && Core::checkPageValidity($_REQUEST['target'], [], true)
I have no idea how to fix this as I'm a vb.net dev with no php experience. Please help. Thanks!
[EDIT] I just found an email from last week about my host upgrading MySQL 5.7.17 to 5.7.29. Based on what my relative said about not being able to log in since last week, this could be the issue. I have contacted my hosting provider.
