The PHP version on your web server does not support the split()
function. It's likely you've installed a snippet or plugin coded for an outdated PHP version - or your web host has upgraded to a newer PHP version.
You'll need to find this snippet/plugin and replace it with explode()
. Easiest way would be to search the relevant tables in the database for the line:
$tempSnippetParams= split($splitter, $tempSnippetParams);
