HTTP ERROR 500

Hi there,

I have been using PHP 7.3 for sometime without error.

Until a few days back. Hence I reverted my PHP back to 7.1.33 and created a staging site.
and found out that TranslatePress is causing this error.

This is from the debug.log

[27-Jun-2020 11:19:13 UTC] PHP Fatal error: Allowed memory size of 805306368 bytes exhausted (tried to allocate 20480 bytes) in /home/customer/www/staging7.3thanwong.com/public_html/wp-content/plugins/translatepress-multilingual/includes/class-translation-manager.php on line 514

memory limit already set to 256M
