[HH#922659] WP debug error

[HelioHost]

Username: ojplanet, Server: Tommy, Main domain: ojplanet.ga

My site goes down more often after a few clicks... Error 500, Error 404/ page not found, so I tried to debug my site to pinpoint the error after so many reinstalled of wordpress

This is the error log...

[16-Jun-2021 00:08:35 UTC] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 843776 bytes) in /home/ojplanet/public_html/wp-content/plugins/elementor/core/common/modules/ajax/module.php on line 265
