Fatal Error mit Litespeed Cache

Moin.

Fatal error:

PHP Fatal error: Cannot redeclare update() (previously declared in /wp-content/plugins/dr-flex/dr-flex.php:641) in /wp-content/plugins/dr-flex/dr-flex.php on line 641\n

Ich habe den Plugin Code folgendermaßen geändert:

update() -> drflex_inner_update()

Um den Fehler zu beheben, darf dazu drflex_inner_update() nur einmal definiert sein. Unabhängig davon, wie oft drflex_update_resources() aufgerufen wird.Somit habe ich drflex_inner_update() mit einer Bedingung versehen, die prüft, ob die Funktion bereits existiert.

function drflex_update_resources()
{
    if (drflex_plugin_database_needs_update()) {
        drflex_debug("Database needs update. Updating...");
        if (drflex_cache_upgrade()) {
            drflex_debug("Update successful.");
        } else {
            drflex_error("Error occurred updating database");
        }
    }

    // Bedingte Definition der inneren Funktion
    if (!function_exists('drflex_inner_update')) {
        function drflex_inner_update()
        {
            // Hier steht der ursprüngliche Code von drflex_inner_update()
