Support » Plugin: Event Organiser » Deprecated use of braces and more

  • Hi,

    When having wordpress debug on this plugin gives a ton of errors and breaks the functionality of wordpress.
    Now, this is only when debug is on, but it makes it much harder to develop when using this plugin.
    One issue is

    ( ! ) Deprecated: Array and string offset access syntax with curly braces is deprecated in C:\xampp\htdocs\fp-dev\wp-content\plugins\event-organiser\includes\class-eo-ical-parser.php on line 331
    Call Stack
    #	Time	Memory	Function	Location
    1	0.0011	520072	{main}( )	...\plugins.php:0
    2	0.0017	559200	require_once( 'C:\xampp\htdocs\fp-dev\wp-admin\admin.php' )	...\plugins.php:10
    3	0.0019	569840	require_once( 'C:\xampp\htdocs\fp-dev\wp-load.php' )	...\admin.php:34
    4	0.0022	580968	require_once( 'C:\xampp\htdocs\fp-dev\wp-config.php' )	...\wp-load.php:37
    5	0.0027	660024	require_once( 'C:\xampp\htdocs\fp-dev\wp-settings.php' )	...\wp-config.php:99

    and then you get a lot of these:

    ( ! ) Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\fp-dev\wp-content\plugins\event-organiser\includes\class-eo-ical-parser.php:331) in C:\xampp\htdocs\fp-dev\wp-includes\functions.php on line 6221

    I’m using PHP 7.4.2 and WordPress 5.4.1 on Apache 2.4.4.1 on windows (xampp)
