Fatal error EE4 with PHP 7.1

My hosting provider is upgrading to PHP 7.1 and EE doesn’t seem to be compatible. I get the following error:

Fatal error: Uncaught Error: [] operator not supported for strings in /home/lernenim/public_html/wp-content/uploads/espresso/templates/espresso-events-table-template-toggle.template.php:88 Stack trace: #0 /home/lernenim/public_html/wp-content/plugins/event-espresso-core-reg/core/helpers/EEH_Template.helper.php(384): include() #1 /home/lernenim/public_html/wp-content/plugins/event-espresso-core-reg/core/helpers/EEH_Template.helper.php(296): EEH_Template::display_template(‘/home/lernenim/…’, Array, true) #2 /home/lernenim/public_html/wp-content/plugins/eea-events-table-view-template/EES_Espresso_Events_Table_Template.shortcode.php(253): EEH_Template::locate_template(Array, Array) #3 /home/lernenim/public_html/wp-includes/shortcodes.php(319): EES_Espresso_Events_Table_Template->process_shortcode(Array, ”, ‘ESPRESSO_EVENTS…’) #4 [internal function]: do_shortcode_tag(Array) #5 /home/lernenim/public_html/wp-includes/shortcodes.php(197): preg_replace_callback(‘/\\[(\\[?)(ESPRES…’, ‘do_shortcode_ta…’, ‘<p> </p>\n<.. in /home/lernenim/public_html/wp-content/uploads/espresso/templates/espresso-events-table-template-toggle.template.php on line 88

What can I do to solve that?

Hi there,

Its from the custom espresso-events-table-template-toggle.template.php you have in wp-content/uploads/espresso/templates/

On line 88 you likely have $category_slugs = '';

If so, change that to $category_slugs = array();

We had the same report from another user using that same custom template so I’m assuming it’s the same problem as it’s the same error, if not we’ll need to see the contents of that template file.

Hi greyowl,

That’s not actually Event Espresso throwing the fatal error, it’s your custom template in
wp-content/uploads/espresso/templates/espresso-events-table-template-toggle.template.php on line 88.

You probably have an array initialized as a string somewhere in the file and that can be easily changed to be initialized as an array.

e.g. change this:

$array_of_items = '';

to this:

$array_of_items = array();

Thanks. That’s fixed it.
